All-Out Assault + Appa, Loyal Sky Bison

All-Out Assault

Appa, Loyal Sky Bison

How it works

1. Declare Appa as an attacker, triggering its ability, airbending All-Out Assault.
2. Move to your postcombat main phase, and activate any number of creatures by tapping them, adding at least 2.
3. Cast All-Out Assault from exile by paying 2.
4. When All-Out Assault enters, it triggers, causing you to get an additional combat and main phase after this one.
5. Move to your next combat phase. At the beginning of that phase, All-Out Assault triggers, untapping each creature you control.
6. Repeat.
