While there's definitely the potential for "take that" with these cards, the ones you showed here could be used beneficially in some circumstances too. Juggernaut and Sabertooth's Rare card ability to KO other players' Allies is great for deck-thinning, for instance (although definitely better earlier in the game, which is a bit less likely since those are expensive rare cards). And those cards, as well as Magneto's Rare, could be used for a big game-ending attack, meaning the KOs or Bindings would be irrelevant. Ultron's Rare could help out another player who got stuck with a bad card draw. So playing with Villains doesn't necessarily *have* to be less co-operative than stock Legendary. Either way, it's nicely thematic.
Nice to see you back
