I wanted to capture the classic team-up and betrayal when faced with a common enemy. The only problems I can find are when a player is your teammate but also the teammate of your opponents. It does cause the game to tie if you manage to give all your opponents a copy in multiplayer but that seems like a feature rather than a bug,

Fun/mean political card! This does have an odd dynamic where, if an opponent were to lose during their own turn and trigger the transformation, the back side's triggered ability would most likely just kill that player anyway. I think the equip ability that anyone can activate is complicating things a bit much, as the "when this transforms into" trigger can backfire on you anyway.
