How it works
Activate Goblin Bombardment by sacrificing Slurrk.
When Slurrk dies, its innate ability and persist ability trigger.
Resolve Slurrk's innate ability, putting a +1/+1 counter on each creature you control that already has a +1/+1 counter on it.
Resolve Slurrk's persist ability, returning it from your graveyard to the battlefield with four +1/+1 counters on it due to its replacement effect.
Resolve the Goblin Bombardment ability.
Repeat.
This looping engine thrives by leveraging the duality of Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight, whose backside grants persist to your other nontoken creatures, allowing Slurrk, All-Ingesting to return from the graveyard with a -1/+1 counter. Because Slurrk enters with five +1/+1 counters to begin with, the resulting state replacement allows it to retain a net positive of counters, ensuring that its own death trigger can continually place new +1/+1 counters on itself and your other creatures. Goblin Bombardment provides the final sacrifice outlet to repeatedly trigger this cycle and convert it into infinite damage against any target.
