Aislyn, Eldritch Queen

Slaughter 2 (This card cost {2} less for each creature that's died this turn.)
When Aislyn, Eldritch Queen enters the battlefield, Put three 2/2 colorless Eldrazi Horror creature tokens on the battlefield with "Sacrifice this creature: Regenerate Aislyn, Eldritch Queen."
So easily do the Eldrazi submit to me.
