Wormfang Manta + Mirage Phalanx + Hushbringer

Wormfang Manta

Mirage Phalanx

Hushbringer

How it works

1. At tbe beginning of your combat phase, Mirage Phalanx and Wormfang Manta trigger.
2. Resolve the Mirage Phalanx trigger, creating a token copy of it with haste and that doesn't have soulbond.
3. Resolve the Wormfang Manta trigger, creating a token copy of it with haste.
4. The Wormfang Manta token's first ability does not trigger due to Hushbringer.
5. At the end of your combat phase, the Mirage Phalanx and Wormfang Manta tokens trigger, exiling themselves.
6. The Wormfang Manta token's second ability triggers, causing you to take an extra turn after this one.
7. Repeat each turn.

This engine achieves an infinite turn loop by exploiting a brilliant loophole in Hushbringer's text. Normally, Wormfang Manta comes with a harsh penalty—skipping your next turn when it enters—but Hushbringer's static ability cleanly suppresses those enter-the-battlefield triggers so you never skip a thing. Meanwhile, Mirage Phalanx pairs up with the Manta via soulbond to churn out hasty token copies of both creatures at the beginning of every combat phase. When those tokens gracefully exit the battlefield at the end of combat, the Wormfang Manta token's leaves-the-battlefield ability finally triggers without interference, safely granting you an extra turn to repeat the entire process indefinitely.
