The 4 combo pieces

What must be in place

Helm of the Host attached to Éomer.
Kari Zev does not have summoning sickness and cannot be blocked and killed by an opponent.

How to execute it

  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.
