Kaya the Inexorable + Wormfang Manta + Hushwing Gryff + Woe Strider

Kaya the Inexorable

Wormfang Manta

Hushwing Gryff

Woe Strider

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 Woe Strider 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 Woe Strider ability, causing you to scry 1.
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 neat loop where sacrificing the Manta to Woe Strider returns it straight to your hand while granting you an extra turn. Usually, replaying the Manta would backfire by forcing you to skip your next turn, but Hushwing Gryff's passive ability brilliantly mutes that entering-the-battlefield drawback entirely. This lets you endlessly recast the Manta from your hand on each extra turn you generate, locking down the game with infinite turns.
