Kaya the Inexorable + Wormfang Manta + Hushwing Gryff + Goblin Bombardment

Kaya the Inexorable

Wormfang Manta

Hushwing Gryff

Goblin Bombardment

How it works

1. Activate Kaya the Inexorable's first ability by putting a loyalty counter on it, putting a ghostform counter on Wormfang Manta.
2. Activate Goblin Bombardment by sacrificing Wormfang Manta.
3. When Wormfang Manta dies, its second ability and its ghostform ability trigger.
4. Resolve the ghostform trigger, returning Wormfang Manta from your graveyard to your hand and creating a 1/1 Spirit creature token.
5. Resolve the second trigger, causing you to take an extra turn after this one.
6. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
7. Cast Wormfang Manta by paying 5.
8. Wormfang Manta's first ability does not trigger due to Hushwing Gryff.
9. Repeat each turn.

This loop relies on breaking Wormfang Manta's built-in drawback by using Hushwing Gryff's static ability to suppress its enters-the-battlefield trigger, ensuring you never skip a turn when you cast it. Instead, you use Goblin Bombardment to sacrifice the Manta, triggering its leaves-the-battlefield ability to bank an extra turn. Kaya the Inexorable's +1 ability provides the recurring safety net via a ghostform counter, which returns Wormfang Manta directly to your hand upon death so you can replay it every single turn.
