Unfinity (UNF) (October 2022) [74 Cards]

Unfinity introduced around 125 new cards that are eternal-legal. Before we can implement these card we would need to implement the attraction and sticker mechanic. Both are somewhat tricky to code.

Attraction break the "Same Card = same logic" Rule which having different cards with different Attraction Lights on.

Legacy, Vintage and Pauper has banned all cards that put Stickers or Attractions into play but not actually the Stickers or Attractions themselves (or other things that reference them). Practically, all Sticker and Attraction cards are not legal in non-Commander formats. Given those changes, only the Dice Roll Changes below are legal in Vintage+

Missing variant cards

Missing nonlegal and funny cards

List of all "Funny" cards, organized by estimated viability of implementing them in Forge, and roughly grouped by mechanic.

This is not intended as a to-do list, as an indication of how soon these cards will be implemented, as an indication of whether they will ever be implemented, as a thorough assessment of implementation difficulty, as a comprehensive list of complications that may emerge when attempting to implement these cards, nor as indicative of the maintenance costs associated with adding such edge cases to the project's code-base.

Comparisons between mechanics needed to support these cards and existing mechanics are not indicative of simplicity. Cards within tiers are loosely grouped by mechanic as a reference, so that implementations designed for one might be made flexible enough to account for others.

The tiers below are not indicative of the amount of overall work needed to implement the cards or features within. They are a broader assessment of how the mechanics and spirit of the card are suited to Forge, to a rules engine, and to a digital environment altogether.

Potential alterations to keep the spirit of the card are considered, and the position of the card may be adjusted accordingly. For example, Infernal Spawn of Evil has the player say "It's coming!" as a flavorful addition to a cost, and is placed in tier 2 because the card mostly maintains its spirit without the spoken dialog. Toy Boat has the player repeatedly say the words "Toy Boat" quickly as a tongue twister, and is placed down in Tier 6 because removing spoken dialog defeats the purpose of the card.

This document is subject to updates as challenges to implementing these cards are discovered or resolved.

134. The Cinematic Phoenix
135. The Legend of Arena
136. Cardboard Carapace - Counts copies in the sideboard. Not exactly as written but very little room for improvement. Adventure+Quest Inventories?
137. Shoe Tree - Can't use actual shoes for counters sadly.
138. "Ach! Hans, Run!" - Just have to name the card.
139. Booster Tutor - Might want to expand to letting the player choose the pack instead of a random one, for consistency with Lore Seeker.
140. Earl of Squirrel - Static trigger instead of a keyword, but shouldn't matter.
141. Urza, Academy Headmaster - Just chooses a random effect from his list, no internet connection required.
142. B.O.B. (Bevy of Beebles) - Link between loyalty counters and beebles is implemented as a state based action and static trigger. Probably fine? May need an exception to implement Rules Lawyer.
143. War of the Spark - "from War of the Spark" is currently implemented as "originally printed in War of the Spark". Unclear if that's supposed to mean the same thing. Compare "Apocalypse Chime", "Heroes of Kamigawa", "Keeper of the Secret Lair"

Tier 0.5: Done*

1. Blacker Lotus - Only removes from match. Should delete from deck and/or collection in limited and adventure-like modes.
2. Ass Whuppin - Implemented as "Destroy target silver bordered permanent," leaving off the Acorn errata and the ability to target other games.
3. Spatula of the Ages - Implemented to look for silver border, but has since been errata'd to include acorn cards. (See also: "Un-Cards", Tier 2.)
4. Border Guardian - Borders are only tracked on an edition level. Silver-bordered SLD cards and borderless prints won't behave correctly. (See also: "Border Color Matters", Tier 3)
5. Planequake - "Uncovered Cavern" plot booster still doesn't exist.
6. Sword of Dungeons & Dragons - Dragon token is colorless, not gold. See "NonWUBRG Colors" in Tier 5.

Banned and Restricted as an effect

(These cards "ban" themselves or other cards via their text, but won't register alongside format bans. Can matter for wish effects.) Once More With Feeling Look at Me, I'm the DCI Gleemox

Host Cards

(These work fine on their own, but can't reach their full potential without the Augment cards)

1. Adorable Kitten
2. Shaggy Camel
3. Mer Man
4. Numbing Jellyfish
5. Big Boa Constrictor
6. Dirty Rat
7. Stinging Scorpion
8. Bumbling Pangolin

10. Eager Beaver
11. Mother Kangaroo
12. Wild Crocodile
13. Angelic Rocket
14. Gnome-Made Engine
15. Labro Bot
16. Voracious Vacuum

Contraption Adjacent

(These work fine on their own, but can't reach their full potential without Contraption cards)

1. Jackknight
2. Steamflogger Boss - (Not an Un-card)

Tier 1

Either works within the rules, or could be scripted without engine changes.

1. Burning Cinder Fury of Crimson Chaos Fire
2. Ricochet
3. Free-Range Chicken
4. Gerrymandering
5. Team Spirit
6. Urza's Science Fair Project
7. GO TO JAIL

19. Gifts Given
20. Ersta, Friend to All
21. Fabled Path of Searo Point
22. Svega, the Unconventional
23. Jester's Sombrero - May be able to do this with RemoveFromMatch?
24. Gallery of Legends - Similar to Killer Cosplay? (Attraction)
25. Gunk Slug - Similar to Time Sidewalk and Bone Rattler?
26. Problematic Volcano - Similar to Raging River?

Rerolling Dice (statically)

(Difficult, but feature is needed for some legal UNF like Monitor Monitor and Xenosquirrels)

1. Clam-I-Am - Option to reroll threes.
2. Wall of Fortune
3. Snickering Squirrel
4. (See also: Socketed Sprocketer, Tier 2)
5. (See also: "Rerolling Dice (using the stack)", Tier 4.)

Card Packs

(We have Booster Tutor. MakeCard can probably support these?)

1. Summon the Pack
2. Opening Ceremony

Tier 2

Spiritually works within rules, new variations on existing features, and/or minor engine changes needed.

1. Psychic Network - Top cards of decks visible to all opponents. Maybe not by holding it against the player's head but revealing it would work fine.
2. Get a Life - Exchange life with teammates. Unclear how this exchange works with more than 2 players on a team, but could probably dig that info up somewhere.
3. Curse of the Fire Penguin - Enchantment that replaces typeline, stats, and textbox. Unsure if this is a different layer than normal.
4. Six-y Beast - May need its own AI flag. It would want to favor higher numbers both when placing counters and guessing them. Also needs to account for counter-doublers in play.
5. By Gnome Means - "Choose any kind of counter a printed card refers to"
6. Rules Lawyer - Think there are a few complications to just skipping over SBA's, but seemed doable.
7. Kindly Cognician - Text matters, but only the Oracle text, not the printed text like most Un-cards.
8. Socketed Sprocketer - Already have diceroll storage from Centaur of Attention, just need uninstall as a cost and the diceroll changes for Monitor Monitor
9. Spike, Tournament Grinder - Wishes for banned cards.
10. Squirrel-Powered Scheme - +2 to all dice rolls. Might be possible with current replacement effects?
11. Standard Procedure - "currently legal in Standard"
12. Far Out - Makes Modal Choices into "Choose one or more". Maybe just a replacement effect on Charm?
13. Animate Object - Effect doesn't really care what the object is. Could just be a token. Might be fun to have a selection of images of random household items to represent the token. (But also Stickers)
14. Pie-Eating Contest - Can't physically eat food to pay the X cost, but can still sacrifice food tokens.
15. Tug of War - Start subgame with 3 chosen cards in battlefield.
16. Nearby Planet - Rangeling (Is all land types)
17. Ral's Vanguard - Vanguard with "Requirement"
18. Enroll in the Coalition - Player is a Flagbearer.
19. Ruff, Underdog Champ - Count games lost this match.
20. Learned Learner - Maximum hand size other than 7. Does this include "no maximum hand size"?
21. Squidnapper - Ransom keyword ability, a cost an opponent may pay statically to nullify an ongoing effect.
22. Blood Poet - Spark abilities.
23. Everlasting Lich - "Can't die."
24. Spellmorph Raise Dead - Basically morph for instants and sorceries.
25. Swarm of Locus - Creature with Land Type
26. Witty Demon - Starting deck size compared to minimum, similar to Yorion.
27. Motivate - Can't attack or block until one-time cost is paid.
28. P-Red Herring - Swaps itself from the hand with a permanent in play, swapping targets on the original to itself.
29. Trial and Error - Triggers when countered or fizzled. Elemental Card Type.
30. Geometric Weird - "Greatest number of spells and abilities from different sources that were on the stack simultaneously this turn"
31. Bear with Set's Mechanic - Aggressive keyword. Similar to Last Night Together? Could possibly do it through a unique effect like Gollum, Obsessed Stalker.
32. Experiment Five - Mana from a source that could produce two or more colors of mana. Similar to snow costs, crossed with production awareness like Exotic Orchard?
33. Patient Turtle - Player went first this game.
34. Kaya, Ghost Haunter - Haunt target creature, target haunted creature.
35. P-Pick Your Poison - Modal options worth points, points must add up to exact value.
36. Seek Bolas's Counsel - Planeswalk in a non-planechase game.
37. Rift - Can start in your opening hand.
38. Snow Mercy - Cost of Tap, Untap, Tap, Untap, Tap.
39. Stocking Tiger - Comes with booster pack when it enters, opens it when it deals damage.
40. Heroes of Kamigawa - "Name printed in a Kamigawa expansion". Maybe a variation on Apocalypse Chime's set filter, to include reprints? Also booster pack, but of a specific type.
41. Keeper of the Secret Lair - Another set filter like above, but matching the set of the current print.
42. Princess Twilight Sparkle - Unclear if everybody winning is the same as a draw, but otherwise works fine within the rules. Shame the cards it depends on don't.

Flip Self

(Doesn't care about where it lands, only whether it's face up or down. Essentially a coin flip.)

1. Orcish Paratroopers
2. Trapeze Artist

Specific Action or Dialog as payment

(Could implement these as zero costs. Would be more fun to declare actions with popups or chat messages though.)

1. Knight of the Hokey Pokey
2. Mesa Chicken
3. Infernal Spawn of Evil
4. Urza's Contact Lenses
5. Emcee
6. Rod of Spanking
7. Impounding Lot-Bot
8. (See also: Magic Word, Tier 3)

Compliments, Insults, Apologies

(Similar to above, but less specific wording. Could be done in spirit by keeping pre-defined list of phrases and let the player choose one.)

1. Miss Demeanor - Possibly an activated ability.
2. Mother of Goons
3. Chivalrous Chevalier
4. An Incident Has Occurred

Trackers, Markers, and Unique Designations

1. The Fallen Apart - Arms and Legs
2. B-I-N-G-O - Chips on bingo board in art
3. Togglodyte - ON/OFF
4. Baron Von Count - Doom Counter
5. Loopy Lobster - Stages
6. Bucket List - Check off card types
7. Rainbow Dash - Player Coolness

Panglacial Worm-likes

1. Infernal Spawn of Infernal Spawn of Evil - (Also dialog as payment)
2. Biting Remark - Cast while scrying.
3. Sunimret - Cast from bottom of library.

Split Card made from Two Existing Cards

(Might work fine as-is?)

1. Bind // Liberate
2. Start // Fire - From two halves from other split cards

Cards in Non-owner's Hidden Zones

1. Five-Finger Discount
2. Spy Eye
3. Very Cryptic Command C
4. Sly Spy E
5. X
6. Centrifuge - (Attraction)
7. Naughty // Nice
8. Last-Minute Chopping

Other Un-Games

(It would be fun to include concurrent games running in other tabs. Aside from that, seeing only the current game misses the spirit of the card but technically works fine, and these would otherwise be in Tier 6 or 7.)

1. Side Quest
2. Exit Through the Grift Shop

Turn Over Card

(Transform if it's a DFC, becomes a 2/2 if it's a normal card, splits up melded cards...)

1. Very Cryptic Command D - Also put card in controller's hand
2. Optimus Prime, Inspiring Leader

Un-Cards

(Looks for Silver Bordered or Acorn cards, but not playtest or Heroes cards. This category probably needs to be defined anyway.)

1. Everythingamajig B
2. Underdome
3. (See also: Spatula of the Ages, Tier 0.5)

Extra Zones

1. Whammy Burn - Whammy deck.
2. Myntasha, Honored One - Booster pile, Booster cascade, Open a Booster as a cost.
3. Mountain Mover - "Underneath" Mountain Mover. Could approximate by storing Mountains in exile instead.

Change Commanders

1. You're in Command
2. Champions of Archery // Join the Group

Partner Variant

(Needs some fleshing out of the Partner conformity checks and deckbuilder logic)

1. Sol, Advocate Eternal - Partners with any creature.
2. Wizard from Beyond - Background that partners with any nonlegendary creature.

Contraptions

(With Attraction deck support, much of the groundwork is in place for these)

1. Accessories to Murder
2. Applied Aeronautics
3. Arms Depot
4. Auto-Key
5. Bee-Bee Gun
6. Boomflinger
7. Buzz Buggy
8. Deadly Poison Sampler
9. Dictation Quillograph
10. Dispatch Dispensary
11. Division Table
12. Dogsnail Engine

15. Faerie Aerie
16. Genetic Recombinator
17. Gift Horse
18. Gnomeball Machine

26. Jamming Device
27. Lackey Recycler
28. Mandatory Friendship Shackles
29. Neural Network
30. Oaken Power Suit
31. Optical Optimizer
32. Pet Project
33. Quick-Stick Lick Trick
34. Rapid Prototyper
35. Record Store
36. Refibrillator
37. Sundering Fork
38. Targeting Rocket
39. Thud-for-Duds
40. Top-Secret Tunnel
41. Tread Mill
42. Turbo-Thwacking Auto-Hammer
43. Twiddlestick Charger
44. Widget Contraption
45. Sap Sucker - Does color identity apply to contraption decks?

Contraption Support

1. Aerial Toastmaster
2. Midlife Upgrade
3. Riveting Rigger
4. Chipper Chopper
5. Incite Insight
6. Spell Suck
7. Suspicious Nanny
8. Finders, Keepers
9. Overt Operative
10. Steady-Handed Mook
11. Garbage Elemental B
12. Steamflogger of the Month
13. Steamflogger Temp
14. Steamfloggery
15. Work a Double
16. Wrench-Rigger
17. First Pick
18. Joyride Rigger
19. Steamflogger Service Rep
20. Clock of DOOOOOOOOOOOOM!
21. Cogmentor
22. Contraption Cannon

Tier 3

Possible to implement, but needs whole new features and/or substantial engine changes.

1. The Ultimate Nightmare of Wizards of the Coast® Customer Service - Y and Z costs. Comet Storm is functionally the same 99% of the time, but why implement this at all if you're not accounting for the other 1%?
2. Collector Protector - Giving away a card. Could work similar to Ante. Only really meaningful in limited and adventure-like formats.
3. Rocket-Powered Turbo Slug - Essentially a Pact, but as a keyword and the cost can be paid any time on the next turn. Unclear how this interacts with cost adjustments. FAQ also adamant that Super haste is not a form of Haste.
4. Gleemax - Control all targets.
5. Magic Word - Choose arbitrary word, whisper it as cost. Could make it another zero cost but loses spirit of card.
6. The Grand Calcutron - Hands are all public, ordered, have to be played in order, and cards added to hand are put at a position chosen by the player.
7. Infernius Spawnington III, Esq. - Number of cards "revealed" this turn.
8. Goblin Blastronauts - "Copy the spell, ability, or Attraction visit that caused you to roll that die." Might be possible to get this in RollDiceEffect and pass it on?
9. Sole Performer - Taps for {T}{T}, a resource used to pay {T} costs.
10. Claire D'Loon, Joy Sculptor - Tokens become "Tokens that are also Cards", which count as tokens but can exist outside the battlefield. Mystery Booster apparently has "Token Cards" (See: Time Sidewalk); are those the same thing?
11. Metagamer - Could just hard-code the list since the errata promised in the rulings is still forthcoming. If/when it does happen though, would need to be maintained, or a solution for auto-updating it would need to be implemented.
12. Do-Over - Restart the turn. Possible with Undo Restore logic?
13. Memory Bank - Affects future game in match. See also, "Between Games" in Tier 4.
14. High Troller - All targets chosen randomly. (Number of targets still chosen by player)
15. Mana Abundance - ReplaceMana, except it changes who gets it.
16. Siege Elemental - Untapped creatures can't block, tapped creatures can.
17. Maro's Gone Nuts - "Double any effect that doubles." No catch-all way to detect this but there aren't that many effects that this applies to...
18. Zymm, Mesemeric Lord - Opponent orders their hand, reveals it one by one until you stop them.
19. Weaponized Scrap - Upgrade. Similar to mutate for artifacts? Somewhat different merge rules though.
20. Decorated Knight // Present Arms - Swap deck with one outside the game, while still being able to draw from it. Could possibly use the extra zones used by Backup Plan?

Cast Cards as Other Cards

(The latter rules that the Evoke cost may be paid. The former does not rule Alternative Costs either way.)

1. Richard Garfield, Ph.D. - Any card with same mana cost.
2. Form of the Mulldrifter - Specifically as Mulldrifter.

Text Boxes

(Usually just refers to all the abilities and keywords, and Exchange of Words does this in black border. But it has different rulings in Un-Games, where flavor text and watermarks also matter.)

1. Do-It-Yourself Seraph
2. Pheobe, Head of S.N.E.A.K. - (Also Flavor Text Matters)
3. Grusilda, Monster Masher - Merges two dead creatures into one living one.
4. It Came from Planet Glurg - Becomes a copy of X different creatures.

Multi-Split Cards

(Most split card logic currently assumes only two parts)

1. Who // What // When // Where // Why
2. Smelt // Herd // Saw

Phases out of Turn

1. Clocknapper - Steal phase from opponent
2. Throat Wolf - Create its own combat phase during opponent's turn (Also Firstest Strike)
3. Chronobot - Switch upkeep steps with an opponent

Animate Zone

(Attaching an enchantment to a zone is a bit weird, but the resulting creature in these cases doesn't seem to be all that complicated to handle...)

1. Animate Library
2. Animate Graveyard

Last or Triple Strike

(Might not be that difficult, but would want it to only show up in the phase UI when relevant)

1. Extremely Slow Zombie
2. Garbage Elemental F
3. Three-Headed Goblin
4. (See also: Throat Wolf)

Activate in Any Zone

(Including while it's in your library and you're about to search for a card with certain characteristics...)

1. _____ - (Also flavor text matters. Also having no name by default.)
2. Shellephant

People Outside the Game Joining the Game

(Could be done by introducing an AI.)

1. Better Than One - (Needs two-headed giant rules support.)
2. Kindslaver

Extend Duration of Effects

(Particularly "until end of turn" or "this turn" effects)

1. Staying Power
2. Grand Marshal Macie - Choose an ongoing effect, it lasts as long as this remains tapped.

Permanently Mark Cards

(Storing the markings with the deck would be ideal, though it will usually only matter in a non-constructed mode, when you're not free to replace the card with a fresh copy each match.)

1. Inspirational Antelope - Same ballpark as Cryptic Spires.
2. Gold Mine - Mark nodes during the game.
3. Autograph Book - Collect signatures from opponents? Adventure enemies?

Cards Outside the Battlefield become Copies

1. Bombardment - Transform your into Missiles.

6. Surgeon General Commander

Host Cards

1. Ordinary Pony
2. Crafty Octopus - Also Contraptions
3. Strutting Turkey

Print Characteristics

(Main complication with these is the golden rule of Un-games, that these characteristics are derived from the printing, not the central Oracle info that normal characteristics use. They may vary from one print to another based on language, edition, or just for stylistic reasons. One permanent can also have multiple sets of these merged into one by something like Grusilda. Only saving grace here keeping this out of Tier 5 is that we could in theory extract most of these from the Scryfall API...)

1. Super Secret Tech - Premium
2. Abstract Iguanart - First letter of artist's name
3. Park Map - Art
4. Collectigull // Only the Best - Booster Fun
5. Treizeci, Sun of Serra - Retro Frame
6. Stet, Draconic Proofreader - First letter of card name, first letter of player's name, and can also delete letters from either.
7. Topdeck the Halls - Premium, promos, alternate frames, and the vaguely defined "alternate art".

Artist Matters

(Forge does keep track of this for most sets.)

1. Circle of Protection: Art
2. Drawn Together
3. Erase (Not the Urza's Legacy One)
4. Fascist Art Director

1. Wordmail
2. Double Header

3. Pygmy Giant
4. Meddling Kids

Rules Text Matters

1. capital offense
2. Nocturno of Myra's Marvels

Reminder Text Matters

1. Duh
2. Old Guard

Flavor Text Matters

1. Ineffable Blessing A
2. Plot Armor
3. Carnivorous Death-Parrot - Does this become an unpayable cost if copied onto a card without flavor text?

Border Color Matters

(Border color is currently supported on an edition level, but not for individual cards. Some cards that use it to look for silver borders have also since been errata'd to include acorns.)

1. Kinght of the Kitchen Sink A
2. Ineffable Blessing C

Watermark Matters

1. Knight of the Kitchen Sink F
2. S.N.E.A.K. Dispatcher
3. Very Cryptic Command E - Also border color
4. "Rumors of My Death..."
5. Hammerfest Boomtacular
6. Druid of the Sacred Beaker
7. Stamp of Approval
8. Secret Base
9. Watermarket

Tier 4

Either poorly defined rules, or other logistical complications exist. Often can be figured out case-by-case but general solutions are hard to come up with.

1. B.F.M. (Big Furry Monster) - Maybe "Can only enter the battlefield simultaneously with its other half," plus a SA to cast them both, plus a replacement that merges them?
2. S.N.O.T. - Unclear what sticking them together means. Merging permanents perhaps?
3. Graveyard Busybody - "All graveyards are also your graveyards." (Also Flavor Text Matters)
4. Over My Dead Bodies - Creatures in graveyards can attack as though they were on the battlefield.
5. Super-Duper Death Ray - Trample on an instant. Very similar to Flame Spill but nuances of it being a keyword need to be investigated. Option to assign more damage to target?
6. Mary O'Kill - Switching places with another card. Conveys all statuses, like an advanced Ninjutsu? Gets a dozen times more complicated when someone drops Conspiracy and names Killbot.
7. Proper Laboratory Attire - Identify cards that allow or require die rolls.
8. Split Screen - Multiple Libraries, choose which one each time you interact with one.
9. Solaflora, Intergalactic Icon - Shares equipment and auras across your board. Could possibly get 90% there with a static ability meddling with EquippedBy or AttachedBy, but plenty of edge cases out there. Does the same with counters and stickers.
10. Mobile Clone - Copying the physically visible characteristics and modifiers of a card and baking them into the copy.
11. Trigger Happy - Trigger an ability. Sounds possible on paper, and rulings cover a lot of edge cases. May just have to try it and see if it breaks.
12. Icing Manipulator - +1/+1 counters are also food tokens. Not even sure how the UI for this would even work. Summon in food tokens to represent them, then add or remove them in lockstep with the counters B.O.B. style?
13. Log Flume - Creatures in a log together can't be blocked unless they're all blocked, and spells that target one of them target all of them. (Attraction)
14. Five Kids in a Trenchcoat - Counts as five creatures when counted.
15. Stack of Paperwork - Combat damage uses the stack.
16. Animate Spell - Enchants a spell on the stack, turns it into a creature.
17. Queue of Beetles - Turns Stack into a FIFO queue.
18. Seasoned Weaponsmith - Creature can be attacked directly
19. Interplanar Brushwagg - Neutral creature that attacks on its own.
20. Soulmates - "Enchant two creatures"
21. Abian, Luvion Usurper - You become a planeswalker, with your life as loyalty counters. B.O.B. style link again?
22. Louvaq, the Aberrant - Different, more complicated definition of "Modified" in its reminder text. Unclear if this should be overwritten by game rules. If so, would fall into Tier 1.
23. Pithing Spyglass - Remove ability words and their corresponding abilities. Could possibly search for them in a trigger or ability description?
24. Elusen, the Giving - "Whenever a player donates a permanent to another player". Whenever a spell or ability they control would give a permanent they control to another player?

Rerolling Dice (using the stack)

(Would probably be best to approximate these as static abilities)

1. Goblin Bookie - Also reflip coin.
2. Pippa, Duchess of Dice
3. Scooch - Even the rulings have no idea how this works.

Between Games

(Effects across multiple games of the same match is straightforward enough. Ideally could include rematches with adventure enemies or similar. Rematches in custom matches however gets iffy - what makes an AI the same individual? Name? Avatar? Human opponents can pose similar problems, and tracking this across different hosts becomes complicated.)

1. Double Dip
2. Double Take
3. Double Cross
4. Double Deal
5. Double Play
6. Ghazban Ogress - Number of games won today
7. Gus - Win streak against player
8. Time Machine

Converting Counters

(Move a counter, and convert it based on the destination's rules text and/or card types.)

1. Giant Fan
2. Everythingamajig A

Swap Player Places

(Exact implementations of these two would be straightforward. However, the FAQ for Unglued and the rulings of the latter suggest that these should swap more than what's described on the card.)

1. Mirror Mirror
2. Everythingamajig F

Lookahead

1. Ambiguity - Reacts to counterspells or permanents that would enter with counters.
2. Mishra's Toy Workshop - Generates mana for token-creating abilities.

Memory

(The AI for "accidentally" forgetting certain bits of info is a bit weird conceptually but not impossible)

1. Squirrel Farm
2. My First Tome
3. Everythingamajig D
4. Memory
5. Common Courtesy - Remembering to ask permission. Possibly implement "Asking" by clicking on Common Courtesy between casting and passing priority?

Attack Active Player

1. Party Crasher - Attacks during opponent's combat phase.
2. Evil Presents - Attacks own controller.

In Multiple Zones at Once

1. Yet Another Aether Vortex
2. Masterful Ninja

Time

(Can use the system clock, but the question is which player's clock to use when online)

1. Elvish House Party
2. Old-Fashioned Vampire - Does isitdarkoutside.com have an API?
3. Syr Cadian, Knight Owl
4. Spirit of the Season - Season of the year. Shifts the complication from timezones to regional calendars...
5. Some Disassembly Required - "If it's December", also distributing keyword abilities.

Instant Creature

1. Visitor from Planet Q
2. Lightning Colt

Tier 5

Theoretically possible to do digitally, but in practice there is no good way to do these in Forge

1. R&D's Secret Lair - Would have to maintain separate cardscripts for every print that functions differently.
2. Vorthos, Steward of Myth - Named character, appearing in art, name, or flavor text. Besides the art (see Art Elements below), would need the list of named characters and any variants of their name to look for.
3. Spelling Bee - Beyond the issues of "Text Matters" from Tier 3 and "Memory" from Tier 4, the biggest issue here is prompting a player to spell a word without showing them how to spell the word. Would need a Text-to-speech implementation.
4. Byode, Inverse Sun - Universes Beyond setting. Would have to be manually maintained, possibly as a list of editions plus individual cards for stuff like SLD.

Noninteger Numbers

1. Bosom Buddy
2. Little Girl
3. Flaccify
4. Cheap Ass
5. Smart Ass
6. Bad Ass
7. Dumb Ass
8. Fat Ass
9. Assquatch
10. Necro-Impotence
11. Wet Willie of the Damned
12. Mons's Goblin Waiters
13. Saute
14. Fraction Jackson
15. Supersize
16. Letter Bomb
17. Mox Lotus
18. City of Ass
19. Infinity Elemental
20. Just Desserts
21. Octo Opus
22. Omniclown Colossus // Pie-roclasm
23. Urza's Fun House

NonWUBRG Colors

(These could be done colorless like Sword of DnD)

1. Water Gun Balloon Game - Pink token (Also "Pop!" counters)
2. Gift Shop - Pink token, (Also Attraction and Stickers)
3. Push Your Luck - Pink token

Number or Text Adjustment

(There's no direct link between numbers within the text and numbers used in the script.)

1. Look at Me, I'm R&D
2. Magical Hacker
3. More or Less
4. Very Cryptic Command F
5. Truss, Chief Engineer

Count Lines of Text

(Scryfall doesn't seem to carry this info.)

1. Lexivore
2. Frazzled Editor - Wordy (4+ lines of rules text)
3. Garbage Elemental A - Wordy
4. Alexander Clamilton - Wordy
5. Hardy of Myra's Marvels - Flavor Text
6. Meet and Greet "Sisay" - Flavor Text (Also Expansion Symbol Matters)

Art Rampage

1. Our Market Research Shows That Players Like Really Long Card Names So We Made this Card to Have the Absolute Longest Card Name Ever Elemental
2. Garbage Elemental E

Art Elements

(If Scryfall included tagger tags in their API, these could go up to tier 3)

1. Knight of the Kitchen Sink C
2. Sly Spy B
3. Sly Spy D
4. Selfie Preservation
5. Acornelia, Fashionable Filcher
6. Don't Try This at Home
7. Ignacio of Myra's Marvels
8. Nightmare Moon - (Also, Friendship)
9. Pinkie Pie

Art Elements, (unsupported by tagger)

1. Bar Entry - Head above the bar in Bar Entry's art.
2. Jermane, Pride of the Circus - Four or more legs.
3. Assembled Ensemble - "artifact creature in its art"; could possibly cross together a bunch of other tags for artificial creature types.

Hat Wearing

(Tagger's "Hat" tag doesn't exactly fit this. Per ruling: "The creature that the card represents must be wearing a hat to have menace. A background character or a scale bird wearing a hat wouldn’t count." Could ignore that caveat and have it fit for the majority of cases though.)

1. Goblin Haberdasher
2. Hat Trick
3. Park Re-Entry
4. T.A.P.P.E.R.
5. Haberthrasher
6. Rat in the Hat
7. Goblin Girder Gang

Arbitrary Words

(Cards where to apply the rules, we'd need to maintain a list of all words in the player's language, because the AI doesn't know to complain if a player chooses "qwxbzrkl")

1. Goblin Cruciverbalist
2. Hangman - Guessing letters of a word is the easy part. Getting the AI to play along is harder.

Time Limits

(Interacting with the Forge UI under time pressure will not be a fun experience for anyone. The AI being able to do it instantly just throws salt in the wound.)

1. Hot Fix
2. Modular Monstrosity
3. Scavenger Hunt - (Attraction)
4. Trivia Contest - (Attraction)

Tier 6

Could at best do a rough imitation, partial implementation, or would require its own minigame to work digitally

2. Jalum Grifter
3. Frankie Peanuts
4. Head to Head
5. Cramped Bunker
6. Boomstacker
7. Devil K. Nevil
8. Tchotchke Elemental
9. Cover the Spot - (Attraction)
10. Squirrel Stack - (Attraction)
11. Chaos Wrap
12. Nerf War
13. Goblin Mime - Triggered by any dialog. Could at least watch for other dialog-costs being paid.
14. Pointy Finger of Doom - Could simulate similar to Chaos Orb, would work better than a lot of others.
15. Phone a Friend - Could just be randomly chosen and/or let the opponent choose?
16. Yule Ooze - Could change the cost from eating food to sacrificing a Food to keep the spirit of the card, but that is a rules change.
17. Fluttershy - Stare down could be implemented as a designation. But even so, "creature with a tail" would make this at best a Tier 5.
18. The Secret Lair - Can't implement accurately without knowing the secret word.

Dexterity; tossing cards at other cards

1. Landfill
2. Chaos Confetti
3. Slaying Mantis
4. Knife and Death

1. Ashnod's Coupon
2. Blufferfish
3. D00-DL, Caricaturist
4. Thopter Pie Network
5. Photo Op - Due to restrictions on Twitter's API, this sadly can't go in Tier 5.
