Altaïr Ibn-La'Ahad

Éomer, Marshal of Rohan

Gogo, Mysterious Mime

Rukarumel, Biologist

How it works

1. At the beginning of your combat phase, Gogo triggers, causing it to become a copy of Altaïr with its name not changing, and causing both Gogo and Altaïr to get +2/+0 and haste until end of turn.
2. Declare Gogo and Altaïr as attackers, triggering their abilities.
3. Resolve the Altaïr trigger, exiling Éomer from your graveyard with a memory counter on it and creating a tapped and attacking copy of Éomer.
4. Resolve the Godo trigger, creating a tapped and attacking copy of Éomer.
5. Put either Éomer token into your graveyard due to the legend rule, triggering the other Éomer token, causing you to untap all creatures you control and to get an additional combat phase after this one.
6. At the end of your combat phase, Altaïr triggers, causing you to exile the Éomer token.
7. Repeat from step 2 each combat phase.
