Safe Return or Painful Choice. Pot of Greed isn't really innately "broken" in the same way those two are - Return will generate a lot of card advantage really fast that far exceeds Pot of Greed, but Painful is more generic and provides setup for pretty much everybody. Future Fusion, for example, was tremendously overpowered for the exact same reasons Painful was, and it was limited to a small number of decks. Still got rightfully banned due to the expanding Fusion pool before getting errata'd (it's still really good afaik even with the turn delay)

-Judgement is, I'd argue, the worst ever designed card in the game's history, but it's isolated to one deck.

-Grass is horribly broken but is specialist like Judgement and not as offensively bad in card design

-Greed/Graceful are extremely powerful but not game-changing like Painful is since Painful will result in pinpoint card advantage vs. hoping you draw well (tutoring > drawing, often)

-idk why Rejuv is still banned (Droolers are what made that card so stupid, more of a symptom than a thing that ruins the game)

-Mirage of Nightmare might be terrible nowadays but maybe not since S/T destruction isrampant and you could probably Twin Twister it. Still kind of combo dependent and slow.

-Last Will is hypothetically not that bad but nearly every deck could probably abuse it and create 2/3 card OTK/FTK combos with it since sometimes the one extra monster is all you need.

-Card Destruction is broken but somewhat luck dependent, potentially bricks, and might carpet bomb good cards as a trade-off
