Gonti's Aether Heart + Mishra, Eminent One + Urza, Prince of Kroog

Gonti's Aether Heart

Mishra, Eminent One

Urza, Prince of Kroog

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. Mishra's Warform enters the battlefield, triggering itself and Gonti's Aether Heart, causing you to get four energy counters.
3. Activate Urza by paying 6, creating a 3/3 Soldier artifact creature token copy of Gonti's Aether Heart.
4. Put the token copy of Gonti's Aether Heart into the graveyard due to the legend rule.
5. The Gonti's Aether Heart token entering the battlefield triggers Mishra's Warform and Gonti's Aether Heart and itself, causing you to get six energy counters.
6. Activate Mishra's Warform by paying eight energy counters and exiling it, taking an extra turn after this one.
7. Repeat each turn.
