Éomer, Marshal of Rohan + Kari Zev, Skyship Raider + Helm of the Host + Goblin Bombardment

Éomer, Marshal of Rohan

Kari Zev, Skyship Raider

Helm of the Host

Goblin Bombardment

How it works

1. At the beginning of your combat phase, Helm of the Host triggers, creating a nonlegendary token copy of Éomer with haste.
2. Declare Kari Zev as an attacker.
3. Kari Zev triggers, creating a legendary 2/1 Ragavan creature token that is tapped and attacking.
4. Holding priority, activate Goblin Bombardment by sacrificing Ragavan.
5. When Ragavan dies, each Éomer that hasn't triggered this turn triggers, untapping all creatures you control and causing you to get at least one additional combat phase after this one.
6. Resolve the Goblin Bombardment ability, dealing 1 damage to any target.
7. Repeat each combat phase.

This dazzling loop relies on Helm of the Host to continually churn out nonlegendary copies of Éomer, Marshal of Rohan, ensuring you always have enough legendary fuel for his untap and extra-combat triggers. Kari Zev, Skyship Raider provides the disposable bodies by riding into battle and spawning Ragavan tokens on every attack. Whenever Goblin Bombardment hurls one of those freshly minted monkeys into the fray as a sacrifice, Éomer's static-fueled trigger condition is met, untapping your entire board and granting you an additional combat phase to repeat the cycle ad infinitum.
