Wormfang Manta + Tocatli Honor Guard + The Mind Stone

Wormfang Manta

Tocatli Honor Guard

The Mind Stone

How it works

1. Blink Wormfang Manta using The Mind Stone. Wormfang Manta's first ability won't trigger due to Tocatli Honor Guard.
2. Wormfang Manta's second ability triggers, causing you to take an extra turn after this one.
3. Repeat each turn.

This ingenious loop turns Wormfang Manta's built-in drawback into an engine for infinite turns, elegantly sidestepping its downside thanks to Tocatli Honor Guard suppressing the creature's enters-the-battlefield trigger entirely. Once your defenses are set, you activate The Mind Stone's harnessed ability during each end step to repeatedly exile and return the Manta to the battlefield; because it only leaves play rather than entering it, you bypass the Honor Guard and safely trigger the Manta's second ability to take an extra turn.
