Grashnak, Warchief of Mayhem

Haste
Whenever a Goblin you control attacks, you may sacrifice it. If you do, it deals damage equal to its power to any target.

Goblin Rage — Whenever a Goblin you control dies, create a 1/1 red Goblin creature token with haste.

"Grashnak leads with reckless abandon, knowing goblins multiply faster than they fall."

For the horde, there’s no such thing as too many explosions.
