Darius, Hand of Noxus

Whenever a creature an opponent controls dies,
if it blocked a creature you control this turn,
put a +1/+1 counter on Darius, then he deals
damage equal to his power to any target.
Ultimate — {b}{b}{r}{g}{w}, {t}: Creatures you
control get +1/+1 and gain double strike,
menace and trample until end of turn. All
creatures able to block them this turn do so.
Untap all creatures.
