Wormfang Manta + Muldrotha, the Gravetide + Hushwing Gryff + Ashnod's Altar

Wormfang Manta

Muldrotha, the Gravetide

Hushwing Gryff

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Wormfang Manta, adding CC.
2. When Wormfang Manta dies, its second ability triggers, causing you to take an extra turn after this one.
3. Cast Wormfang Manta by paying 5.
4. Wormfang Manta's first ability does not trigger when it enters the battlefield due to Hushwing Gryff.
5. Repeat each turn.

This brilliant loop turns Wormfang Manta's built-in drawback into an engine for infinite turns, sidestepping its "skip your next turn" trigger entirely thanks to Hushwing Gryff shutting down entering-the-battlefield abilities. By sacrificing the Manta to Ashnod's Altar, you not only generate the mana needed to recast it but also trigger its leaves-the-battlefield ability, banking an extra turn. Finally, Muldrotha, the Gravetide ties the whole machine together by letting you recast the Wormfang Manta directly from your graveyard turn after turn.
