Defender
At the beginning of combat on your turn, you may clash with an opponent. If you win, this creature gets +2/+0 and loses defender until end of turn. (Each clashing player reveals the top card of their library, then puts that card on their choice of the top or bottom. A player wins if their card had a greater mana value.)
