Rites of Jund

Create X 1/1 red Goblin creature tokens with Haste.
If you spent at least {3}{g}{r}{b} to cast this,
create a 3/3 red Dragon creature token with
Flying, Trample, Haste, and Devour 1. (As
it enters the battlefield, you may sacrifice any
number of creatures. That creature enters the
battlefield with that many +1/+1 counters on it.)
