Phantom Steed

Godo, Bandit Warlord

Lumbering Battlement

Arcane Adaptation

Fervor

How it works

1. Declare Phantom Steed and Godo as attackers, triggering their abilities.
2. Resolve the Godo trigger, untapping all creatures you control and causing you to get an additional combat phase after this one.
3. Resolve the Phantom Steed trigger, creating a token copy of Lumbering Battlement.
4. The token Lumbering Battlement enters the battlefield, exiling Godo until Lumbering Battlement leaves the battlefield.
5. At the end of your combat phase, the token Lumbering Battlement triggers, causing you to sacrifice it.
6. The token Lumbering Battlement leaves the battlefield, returning Godo from exile to the battlefield.
7. Repeat each combat phase.
