Commander legal

The 2 combo pieces

What must be in place

Éomer cannot be blocked and killed by an opponent.
You have at least three opponents.

How to execute it

  1. At the beginning of combat, Duke Ulder Ravengard triggers, giving Éomer an additional instance of myriad until end of turn.
  2. Declare Éomer as an attacker.
  3. Each instance of Éomer's myriad ability triggers, creating at least two token copies of it tapped and attacking each other opponent.
  4. Put all Éomer tokens into your graveyard due to the legend rule.
  5. When the Éomer token(s) die, each Éomer triggers, untapping all creatures you control and causing you to get at least two additional combat phases after this one.
  6. Repeat from step 2 each combat phase.
  7. Once you have an arbitrarily high number of combat phases, you may have Duke Ulder Ravengard give myriad to any other creatures you control.
