Red Kraken, Scourge of Cthulhu

Reach, Trample, Vigilance, Lifelink
When Red Kraken enters the battlefield destroy
all creatures and gain 5 life
The amount of creatures in the graveyard is equal
to its power and toughness
I wouldn't exactly summon this if I had creatures,
they don't know their allies from opponents.
-Hae Jyon, Kraken Tamer
