Gonti's Aether Heart + Mishra, Eminent One + Mirror Room // Fractured Realm

Gonti's Aether Heart

Mishra, Eminent One

Mirror Room // Fractured Realm

How it works

1. At the beginning of combat, Mishra triggers, creating a 4/4 artifact creature token copy of Gonti's Aether Heart named Mishra's Warform.
2. When Mishra's Warform enters the battlefield, it and Gonti's Aether Heart trigger twice each, causing you to get eight E.
3. Activate Mishra's Warform by paying eight E and exiling it, taking an extra turn after this one.
4. Repeat each turn.

This brilliant loop relies on Mishra, Eminent One to repeatedly churn out temporary copies of Gonti's Aether Heart, which quietly tracks every artifact that enters your battlefield. Thanks to the doubling static ability of Mirror Room // Fractured Realm, those entry triggers yield double the energy, immediately fueling the copied artifact's ultimate ability to exile itself for an extra turn. Because Mishra's Warform enters fresh at the start of every combat step, you can endlessly repeat this explosive cycle to take infinite turns and lock down the game.
