Kaya the Inexorable + Wormfang Manta + Torpor Orb + Viscera Seer

Kaya the Inexorable

Wormfang Manta

Torpor Orb

Viscera Seer

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 Viscera Seer 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 Viscera Seer ability, causing you to scry 1.
7. Cast Wormfang Manta by paying 5.
8. Wormfang Manta's first ability does not trigger due to Torpor Orb.
9. Repeat each turn.

This brilliant, albeit monstrous, loop hinges on bypassing Wormfang Manta's built-in drawback while relentlessly harvesting its departure trigger for infinite turns. Normally, playing the Manta would cost you your next turn, but Torpor Orb acts as a vital anchor by muting its entering-the-battlefield trigger, letting it slide onto the board safely. Once it's there, Kaya the Inexorable primes the Manta with a ghostform counter so that sacrificing it to Viscera Seer triggers a return to your hand alongside an extra turn—all without skipping your future.
