Éomer, Marshal of Rohan + Altaïr Ibn-La'Ahad + Ashes of the Fallen + Phantom Train

Éomer, Marshal of Rohan

Altaïr Ibn-La'Ahad

Ashes of the Fallen

Phantom Train

How it works

1. Declare Altaïr as an attacker. Altaïr triggers, exiling Éomer from your graveyard with a memory counter on it, and then creating a tapped and attacking token copy of each card you own that is exiled with a memory counter on it.
2. Activate Phantom Train by sacrificing another legendary creature token except Éomer.
3. When the creature dies, Éomer triggers, untapping all creatures you control and causing you to get an additional combat phase after this one.
4. Resolve the Phantom Train ability.
5. Repeat during each combat phase.

This ingenious combat loop hinges on Ashes of the Fallen, which redefines every creature card in your graveyard—including Éomer, Marshal of Rohan—as an Assassin so that Altaïr Ibn-La'Ahad can continually resurrect them as attacking token copies upon declaring an attack. As those tokens enter the fray, you feed one to Phantom Train, whose activation transforms it into a Spirit while pumping its power with a +1/+1 counter. The sacrifice of that legendary token instantly triggers Éomer's untap and extra combat phase clause, letting you reset your attackers and repeat the cycle indefinitely.
