Akki Battle Squad + Helm of the Host

Akki Battle Squad

Helm of the Host

How it works

1. At the beginning of your combat phase, Helm of the Host triggers, creating a token copy of Akki Battle Squad with haste.
2. Declare another modified creature you control as an attacker.
3. Akki Battle Squad triggers, untapping all modified creatures you control and causing you to get an additional combat phase after this one.
4. Repeat each combat phase.
