Lady Sun + Wormfang Manta + Tocatli Honor Guard

Lady Sun

Wormfang Manta

Tocatli Honor Guard

How it works

1. During your precombat main phase, cast Wormfang Manta by paying 5.
2. Wormfang Manta's first ability does not trigger due to Tocatli Honor Guard.
3. Activate Lady Sun by tapping it, returning it and Wormfang Manta from the battlefield to your hand.
4. When Wormfang Manta leaves the battlefield, its second ability triggers, causing you to take an extra turn after this one.
5. Cast Lady Sun by paying 1.
6. Repeat each turn.

This clever loop relies on Tocatli Honor Guard's static ability to suppress Wormfang Manta's drawback, ensuring that entering the battlefield doesn't force you to skip your next turn. Once the Manta is safely in play, you activate Lady Sun during your precombat main phase to bounce both herself and the Wormfang Manta back to your hand. When Wormfang Manta leaves the battlefield this way, its second ability triggers to grant you an extra turn, bypassing any negative entry triggers entirely. You then simply replay Lady Sun, recast the Manta on your subsequent turns, and repeat the process to take infinite turns and lock down the game.
