How it works
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.
Activate Phantom Train by sacrificing another legendary creature token except Éomer.
When the creature dies, Éomer triggers, untapping all creatures you control and causing you to get an additional combat phase after this one.
Resolve the Phantom Train ability.
Repeat during each combat phase.
This clever sequence turns an aggressive onslaught into an endless loop by uniting tribal manipulation and graveyard resurrection into a combat engine. Rukarumel, Biologist acts as the linchpin, making your creature cards and permanents share the chosen type so that Éomer, Marshal of Rohan benefits from the chaos. When Altaïr Ibn-La'Ahad charges into battle, he continually pulls Éomer from the graveyard to populate the battlefield with a fresh token copy, while Phantom Train provides a convenient outlet to sacrifice a legendary token and trigger Éomer's untap and extra combat phase ability.
