At the beginning of combat on your turn, create a 2/1 red Elemental creature token with trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.) and haste (This creature can attack, and as soon as it comes under your control.). Sacrifice it at the beginning of the next end step. : Search your library for a card, put it into your hand, then shuffle. Activate only if five or more creatures died this turn.
