Phantom Steed + Godo, Bandit Warlord + Lumbering Battlement + Maskwood Nexus + Fervor

Phantom Steed

Godo, Bandit Warlord

Lumbering Battlement

Maskwood Nexus

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.

This brilliant loop transforms Godo, Bandit Warlord into an unstoppable engine for infinite combat phases, made possible by Maskwood Nexus granting every creature the Samurai type so Godo's untap trigger affects the entire board. When Phantom Steed attacks, it conjures a token copy of Lumbering Battlement that promptly exiles Godo, only to release him right back when the token is sacrificed at the end of combat. Fervor ensures everything can rush into battle immediately, while Godo's entry ability exploits each new iteration to pull every single Equipment card straight from your library onto the battlefield.
