Life of the Party

Creature — Elemental

First strike, trample, haste Whenever Life of the Party attacks, it gets +X/+0 until end of turn, where X is the number of creatures you control. When Life of the Party enters, if it's not a token, each opponent creates a token that's a copy of it. The tokens are goaded for the rest of the game. (They attack each combat if able and attack a player other than you if able.)
