Draven, Glorious Executioner

Menace, double strike
Whenever Draven becomes tapped, you may
have him deal damage equal to his power to any
target. If you do, he loses double strike and
gains first strike until end of turn.
Ultimate — {b}{r}, {t}: Until end of turn,
whenever you cast a spell for its spectacle cost,
put a +1/+1 counter on Draven.
