Port Razer + Mirage Phalanx

Port Razer

Mirage Phalanx

How it works

1. At the beginning of your combat phase, Mirage Phalanx and Port Razer each trigger, creating a token copy of Mirage Phalanx and Port Razer with haste.
2. Deal combat damage to an opponent using the Port Razer token.
3. The Port Razer token triggers, untapping each creature you control and causing you to get an additional combat phase after this one.
4. At the end of your combat phase, the Mirage Phalanx and Port Razer tokens each trigger, exiling themselves.
5. Repeat each combat phase.
