Altaïr Ibn-La'Ahad
Port Razer
Roshan, Hidden Magister

Requires
Altaïr Ibn-La'Ahad must be on the battlefield. Port Razer must be in the graveyard. Roshan, Hidden Magister must be on the battlefield. An opponent cannot block creatures you control. You have a way to give Altaïr Ibn-La'Ahad vigilance.
Steps
  1. Give Altaïr Ibn-La'Ahad vigilance by any method.
  2. Declare Altaïr Ibn-La'Ahad as an attacker.
  3. Altaïr Ibn-La'Ahad triggers, exiling Port Razer from your graveyard with a memory counter on it as it is an Assassin due to Maskwood Nexus, and then creating a tapped and attacking token copy of each creature you own in exile with a memory counter on it.
  4. Deal combat damage to an opponent using the Port Razer token.
  5. The Port Razer token triggers, 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 Ibn-La'Ahad triggers, exiling the Port Razer token.
  7. Move to your next combat phase, and declare Altaïr Ibn-La'Ahad as an attacker.
  8. Altaïr Ibn-La'Ahad triggers, creating a tapped and attacking token copy of each creature you own in exile with a memory counter on it.
  9. Repeat from step 4.
Results
Infinite LTB. Infinite ETB. Infinite combat phases. Infinite untap of creatures you control. Infinite mana creatures you control can produce. Infinite combat damage.
