Mishra, Eminent One + Gonti's Aether Heart + Stridehangar Automaton

Mishra, Eminent One

Gonti's Aether Heart

Stridehangar Automaton

How it works

1. At the beginning of your combat phase, Mishra triggers, creating a 4/4 artifact creature token copy of Gonti's Aether Heart named Mishra's Warform and a 1/1 Thopter artifact creature token.
2. When the Thopter and Mishra's Warform enters the battlefield, Mishra's Warform 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, causing you to take an extra turn after this one.
4. Repeat each turn.
