Primal Summoning

Unap and gain control of all squirrels. They gain trample and haste until end of turn.
As you cast this card, you may put the top six cards of your library into your graveyard. If you do, squirrel type creatures you control get +X/+X until end of turn, where X is the number of squirrels you control.
"His call echoes through halls of Plu-Monohn."
