Vandread, Mararion Apex

Trample

At the beginning of combat on your turn, Clash
with an opponent. You may put any number of creatures you revealed this way onto the battlefield. If you win, creatures you control gain +1/+1 and haste until end of turn. (Each clashing player reveals the top card of their library, then puts that card on the top or bottom. A player wins if their card had a higher converted mana cost.)
