Kaya the Inexorable + Wormfang Manta + Tocatli Honor Guard + Ashnod's Altar

Kaya the Inexorable

Wormfang Manta

Tocatli Honor Guard

Ashnod's Altar

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 Ashnod's Altar by sacrificing Wormfang Manta, adding CC.
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. Cast Wormfang Manta by paying 5.
7. Wormfang Manta's first ability does not trigger due to Tocatli Honor Guard.
8. Repeat each turn.

This brilliant loop exploits the notorious downside of Wormfang Manta to bend time infinitely in your favor, fueled by Ashnod's Altar providing the mana to recast it. While Wormfang Manta normally makes you skip your next turn when it enters, the quiet presence of Tocatli Honor Guard elegantly suppresses that dreaded trigger entirely. Meanwhile, Kaya the Inexorable prepares the fish-beast for its cyclical doom by marking it with a ghostform counter, ensuring it safely bounces back to your hand whenever it's sacrificed.
