Eldrazi Spawner

When Eldrazi Spawner enters the
battlefield, attacks, blocks, becomes the
target of a spell or ability, dies, gets exiled,
gets put into the commander zone, returns
to your hand, or gets put on top of your
library, create a 1/1 colorless Eldrazi Scion
creature token. It has "Sacrifice this
creature: Add {c}."
