Other: Infinite combat damage, Infinite combat phases, Infinite ETB, Infinite LTB, Infinite mana creatures you control can produce, Infinite untap of creatures you control

Declare Altaïr Ibn-La'Ahad as an attacker. Altaïr Ibn-La'Ahad triggers, exiling Port Razer from your graveyard with a memory counter on it as it is an Assassin due to Ashes of the Fallen, and then creating a tapped and attacking token copy of each creature you own in exile with a memory counter on it. Deal combat damage to an opponent using the Port Razer token. The Port Razer token triggers, causing you to untap all creatures you control and to get an additional combat phase after this one. At the end of your combat phase, Altaïr Ibn-La'Ahad triggers, exiling the Port Razer token. Move to your next combat phase, and declare Altaïr Ibn-La'Ahad as an attacker. 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. Repeat from step 3.
