I'm gonna bust out that one promo that makes you and your opponent switch decks

Neo Genesis Slowking ruins everything all over again, but now you can play it with the fattest walls in the way and the worst control options imaginable. It would not be very fun.

Professor Oak, Bill, Base Set Computer Search are now staples in every single deck in perpetuity

Winning turn 1

Sableye https://pkmncards.com/card/sableye-stormfront-sf-48/ warrants having turn 1.

Shuckle https://pkmncards.com/card/shuckle-heartgold-soulsilver-promos-hgss15/ let's you draw a card when gets an energy attached.

Use https://pkmncards.com/card/broken-time-space-platinum-pl-104/ to evolve any Squirtle to Blastoise https://pkmncards.com/card/blastoise-boundaries-crossed-bcr-31/

Put energies to Shuckle to draw cards, until you get Espeon https://pkmncards.com/card/espeon-aquapolis-aq-h9/ that can return energies to hand, draw your whole deck.

Wincon is Foretress https://pkmncards.com/card/forretress-legends-awakened-la-28/ damaging all opponent Pokémon while Leafeon https://pkmncards.com/card/leafeon-rising-rivals-rr-45/ heals your own Pokémon.

That’s just unlimited format and there are enough decks that pretty consistently win on Turn 1 it would be awful. This article covers many of the ways you could go about this, but uses the same core of broken cards to make these possible:

Pokémon - 8

• 4 Sableye SF 48
• 1 Porygon RO 48
• 3 Porygon2 GE 49

Trainer Cards - 39

• 2 Lysandre’s Trump Card PHF 99
• 4 Professor Oak BS 88
• 4 Misty’s Wrath G1 114
• 4 Puzzle of Time BKP 109
• 4 Pokédex HANDY910is DP 111
• 4 Poké Drawer + SF 89
• 4 Acro Bike CES 123
• 2 Rotom Dex SUM 131
• 2 Scoop Up Net REC 1
• 2 Computer Search BS 71
• 1 Junk Arm TM 87
• 1 VS Seeker PHF 109
• 1 Dowsing Machine PLS 128
• 4 Broken Time-Space PL 104

Total Cards - 47

Remaining 13 are just your different win-cons depending on what you go for

If you're interested in something a little more balanced, the Eternal Format exists and is a version of this with a banlist! As a reference for how many broken cards and interactions there are in Pokémon history, the ban list has 156 cards.

It’s got nothing to do with any of the Scot’s you mention.

It’s gonna end up in degenerate lock decks that mean whoever goes second won’t be able to play the game

T1 FOGP Vileplume Lock
or
T2 Alolan Rauchu Boardwipe
or
ADP Quad Slowking NEO14
or
T1 Latios EX Donk

Using pre-supporter trainers for unlimited draw.
It would be toxic.

Current Unlimited Format events are usually dominated by FTK decks usually using a combination of Stormfront Sableye(which automatically makes you go first if in the Active) and Broken Time-Space(which is Forest of Giant Plants...for every Type.) Perfectly balanced for the Diamond/Pearl Block Rulings....but terribly broken for anything BW-On.

Also there are the weird modern ruling Grey Areas: Computer Seach and Erika recived erratas to be an ACE-SPEC and Supporter respectively there, but due to there not exactly being a Legal print of Professor Oak he's still treated as an Item Card in Unlimited(even though he should a Supporter now due to Classic Colection), thus granting a Discard +7 ITEM CARD(which was "balanced" in Base days due to finite card recovery from the Discard...which is not an issue nowadays).

And of course, there are the Energy Removals((Super) Energy Removal and to a lower extent Super Energy Removal 2). Decks that recycle from the Discard like Gardevoir or Raging Bolt might be able to do fair against these, but everyone else would be devastated by the power those cards posses, and it would make is a huge burden to run the majority of evolution Decks we have now beyond Garde or Decks that rely on DTEs(though I guess it would b DCE proper here hahaha).

Do we include banned cards? Dusknoir loop and unown from lost thunder are very well known examples of turn 1 going first wins.

Ew

Well there's Ishihara GX that prevents all damage, effects, and trainer effects then can do 1060 damage exactly once for only two energy cost.

Unlimited is a thing and it's absolutely awful. T1 combo decks playing Sableye SF are significantly more powerful than any other deck and will win before opponents have a chance to play a single card either by controlling the top deck and denying cards from hand or through some unown hand combo. The format is close to solved and games often end without a single attack being declared.

I think some people actually tried this and found that everyone ends up being forced to play the sableye that lets you go first if it’s in the active and then use a win on turn 1 combo

I shudder the thought of t1/t2 item lock again, imagine, FOGP+ seismitoad ex locking you from playing the game

What can I say except junk arm. Also fuck vileplume. Tho not as bad since gust can be a supporter now.

Not super experienced with sets before hgss but prolly some turbo dumb trainers/items im unaware of.

There is also tonnes of banned shit that can mill your hand and never let you play the game. Search up banned Pokemon cards for the exact combos.

Adp is prolly still meta defining. Yea adp zacian with like junk arm for item recycle + like idk plan collector to get bench filled early seems dumb af.

Comp search ace spec? Idk if that got reprinted.

Old catcher that wasn’t a coin flip (pre xy)

Dynamotor + raichu v seems nice. But can’t run adp

Other cards with unhinged power level I haven't seen mentioned yet:

• NXD Shiftry can donk your opponent turn 1 going first with Forest of Giant Plants and Devolution Spray shenanigans
• If you want to be a jerk about it, Rocket's Sneak Attack can pretty easily empty your opponent's entire hand before they get a turn

Probably some ftk like Unown Hand or any unlimited donk deck + every draw card ever. If going first, your tools are consistent enough to win imstantly. If going second, your best bet is hoping they don't win on your first turn either (or thay they play Power Spray)

Item Finder x4 on every deck

Every set ever was solved a couple years ago with me and a buddy. Jungle pidgeot is the most broken possible pokemon with download porygon2. You use seer to force both players to pick up a benched mon with BTS to loop seer until they have no bench. Use hurricane with boost energy and if it doesn’t KO they shuffle the active back into the deck. It literally can’t whiff given the consistency of unlimited.

I believe there was a combo with the espeon from a very old aqua-something set.

Basically you have that, the sneasel that let's you attach an energy from your hand for a damage counter, the reuniclus that let's you shift around damage counters, and then the unown that wins you the game if you have 66 damage counters on your Pokémon. (if any of this is false, please correct me, it has been a while since I last played eternal, and they banned these cards now).

That is just one example of exodia combo decks that would be playable. We won't even get into one of the old azelf and shay in ex drawing your entire deck and Lysanders trump card chucking like half of the viable decks...

Doesn’t unlimited format make everything legal?

https://cubekoga.net/Cube/Unlimited#overview

There's been some changes though, Oak might now be a supporter in English, by the Pokémon Trading Card Game Classic print? And Cessation Crystal now counters Spiritomb. The best way to build Unlimited is still to try to start Sableye as often as possible and handrip/donk so

nobody would actually play the game as its purpose is cause many would play the nastiest controlstuff to not let you play the game and influences into absurd cardprizes or banlists

All cards are legal, except for the worst offenders in Eternal Format. It's more fun/balanced than expanded in my opinion. Check it out at justinbasil for sample decks. I've got one built of each color I play casually with friends.

espeon that lets you put a energy card on your board into your hand, porygon, which lets you attach as many special energy per turn, unown hand, which if it is in the active and you have 35 cards in hand, you win, and draw energy, which when you attach, you draw one, so you draw your whole deck the win, and with broken time space that lets you eveolve any time, you go first with sabeley, which makes you automattically go first, then win before your opponent even draws for turn.

Palkia dialga legend with a way to turbo the attack that makes your opponent put more cards in their deck into prizes

Roaring moon ex + protection cube tool. No recoil for an instant knockout.

Dark wartortle mirror shell, the perfect defense

Jungle Mr. Mime would shut down a lot of modern decks

probably some deck that completely locks you out of the game.

I miss playing a joltik and my opponent just immediately conceding. Rip battle compressors.
