Memories of Cataclysm

Memories of Cataclysm enters the battlefield
with two blight counters on it.
At the beginning of your upkeep, you may
remove a blight counter from Memories of
Cataclysm. If you do, destroy all creatures.
Players cannot cast creature spells until the
beginning of your next upkeep.
When Memories of Cataclysm has no blight
counters on it, sacrifice it.
