Wormfang Manta + Torpor Orb + Roon of the Hidden Realm

Wormfang Manta

Torpor Orb

Roon of the Hidden Realm

How it works

1. Blink Wormfang Manta using Roon of the Hidden Realm. Wormfang Manta's first ability won't trigger due to Torpor Orb.
2. Wormfang Manta's second ability triggers, causing you to take an extra turn after this one.
3. Repeat each turn.

This clever loop lets you harvest endless extra turns by exploiting Wormfang Manta's delayed trigger while expertly dodging its major drawback. Normally, entering the battlefield would force you to skip your next turn, but Torpor Orb acts as a quiet suppressor that stops that painful downside from ever triggering. That leaves Roon of the Hidden Realm free to repeatedly exile and return the Manta, so that every time it leaves the battlefield, its second ability fires off to hand you an extra turn.
