Wakka, Auroch Captain

Wakka can block as though he has flying.

Auroch Reels—{3}{r}{u}: Flip a coin until you lose a
flip. Wakka deals damage to you equal to the
number of times you flipped a coin this turn. For
each flip you win, after this phase there is an additional combat phase. At the beginning of each combat phase this turn, untap each creature you control. Activate this ability only as a sorcery.
