Kaya the Inexorable + Wormfang Manta + Hushwing Gryff + Bartolomé del Presidio

Kaya the Inexorable

Wormfang Manta

Hushwing Gryff

Bartolomé del Presidio

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 Bartolomé del Presidio 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 Bartolomé del Presidio ability, putting a +1/+1 counter on it.
7. Cast Wormfang Manta by paying 5.
8. Wormfang Manta's first ability does not trigger due to Hushwing Gryff.
9. Repeat each turn.

By placing a ghostform counter on Wormfang Manta using Kaya the Inexorable, you set up a loop where sacrificing the Manta to Bartolomé del Presidio sends it back to your hand while granting you an extra turn. The true genius of the setup lies in Hushwing Gryff, whose static ability gracefully mutes the Manta's dreaded enter-the-battlefield drawback of skipping your turn. This allows you to safely recast Wormfang Manta turn after turn without penalty, locking down the game in an unbroken chain of infinite turns while growing Bartolomé del Presidio into a massive threat.
