...Is A Crowd

Target player becomes a three-headed hydra
player for the rest of the game. (Target player
chooses two random people from outside the game
and all three people are now one player. Each person
can hold up to seven cards in his or her hand. All
three players must unanimously agree on playing a
card before it can be cast. If an effect were to target
one player, it affects all three players instead. All
three players share the same library, graveyard,
mana sources, life, and turns.)
