Éomer, Marshal of Rohan + Altaïr Ibn-La'Ahad + Leyline of Transformation + Phantom Train

Éomer, Marshal of Rohan

Altaïr Ibn-La'Ahad

Leyline of Transformation

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 loop transforms your combat step into an engine of relentless recursive violence, fueled by Leyline of Transformation uniting your entire team under the Assassin banner so Altaïr Ibn-La'Ahad can continuously clone your fallen heroes. When Altaïr attacks, he resurrects a fallen Éomer, Marshal of Rohan as a tapped and attacking token, setting up the foundation to untap your entire board and grant you an extra combat phase whenever a legendary creature dies. Phantom Train acts as the crucial sacrifice outlet that triggers this death cascade, feeding on creatures to grow larger while instantly triggering Éomer's untap and extra combat abilities. By looping this sequence, you generate infinite combat phases, endless sacrifice and death triggers, and astronomical power for your train.
