Fall of Erozagy

Exile target creature an opponent controls. If
that creature was legendary then exile all
legendary creatures your opponents control.
Create a gold token with "Sacrifice this artifact:
Add one mana of any color" for each creature
exiled this way.
"Erozagy's doom was wisely planned. Mine the place
dry then bury any survivors or witnesses in a ten foot
thick river of molten lava."
