Praetorhoof Behemoth

Haste
When Praetorhoof Behemoth enters the battlefield, you may search your library and reveal any number of Praetors from among cards in your library and hand. Creatures you control gain trample and get +X/+X until end of turn, where X is the number of Praetors you have showing from among your hand, library, battlefield, and graveyard. Then shuffle.
