How it works
Prerequisites
- Helm of the Host attached to Port Razer.
- An opponent is unable to block Port Razer.
Steps
- 1At the beginning of combat, Helm of the Host triggers, creating a token copy of Port Razer with haste.
- 2Declare the Port Razer token as an attacker.
- 3When the Port Razer token deals combat damage, it triggers, causing you to untap all creatures you control and get another combat phase after this one.
- 4Repeat.
