Mithrix

Trample
When Mithrix deals combat damage to a player,
you may remove up to three counters from it.
Put three -1/-1 counters on Mithrix: Create two
1/1 colorless Exploder artifact creature tokens
with "When this creature dies, deal one damage
to any target" or a 3/3 colorless Golem artifact creature token with trample. Activate only as a
sorcery.

brother loved worms.
