Whenever a player casts a creature spell that’s black, red, or green, it gains devour 5. (As the creature enters, its controller may sacrifice any number of creatures of their choice. The creature enters with five times that many +1/+1 counters on it.)
Whenever chaos ensues, create two 1/1 red Goblin creature tokens.
Casting a multicolor spell will cause the first ability to trigger as long as that spell is black, red, or green. It can be other colors as well.

If the creature spell already has devour, you may sacrifice creatures using either ability. Each creature you sacrifice counts for only one devour ability. Under most circumstances, you'll pick the devour ability that gives the greatest number of +1/+1 counters.
