Falkenrath Horror

Flying, first strike, menace
When Falkenrath Horror enters the battlefield, sacrifice all other creatures you control. For each creature sacrificed this way,
put a 3/2 colorless Eldrazi Horror creature token onto the battlefield and a +1/+1 counter on Falkenrath Horror.
As long as you control no non-Eldrazi creatures, Falkenrath Horror has indestructible.
