Odessa, the Golden Seer

Flying, incited (Incited creatures get a +1/+1 counter during each of their owner's upkeeps.)

When Odessa attacks, blocking creatures get -2/-2 until end of turn. If blocking creatures die this turn, exile them instead. Attacking creatures you control get +2/+2 and menace until end of turn.

Odessa counts as two creatures when blocking attacking creatures with menace.
