Éomer, Marshal of Rohan + Altaïr Ibn-La'Ahad + Bartolomé del Presidio + Roshan, Hidden Magister

Éomer, Marshal of Rohan

Altaïr Ibn-La'Ahad

Bartolomé del Presidio

Roshan, Hidden Magister

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 Bartolomé del Presidio 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 Bartolomé del Presidio ability.
5. Repeat during each combat phase.
