Psi vs. Psi

At the beginning of your upkeep, you and
target opponent each create a 9/9 colorless
Avatar God creature token with haste, flying,
and annihilator 3. If the token is the target of
a spell or ability, its controller sacrifices it.
Avatar God creatures can't attack you or
planeswalkers you control.
Saiki K: Good grief.
Mob: There's nothing good about this.
