Kaya the Inexorable + Wormfang Manta + Torpor Orb + Yahenni, Undying Partisan

Kaya the Inexorable

Wormfang Manta

Torpor Orb

Yahenni, Undying Partisan

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 Yahenni 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 Yahenni ability, giving it indestructible until end of turn.
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 ingenious loop locks your opponents out of the game entirely by taking infinite turns without ever paying the heavy cost Wormfang Manta normally demands. With Torpor Orb silencing the Manta's dreaded "skip your next turn" entry trigger, you can safely sacrifice the creature to Yahenni, Undying Partisan; thanks to the ghostform counter previously bestowed by Kaya the Inexorable, the Manta conveniently returns straight to your hand while triggering its second ability to grant you an extra turn. You simply replay the Manta on each subsequent turn, feeding Yahenni a steady stream of sacrifices while stacking infinite turns to completely bury the table.
