The Negotiator

Whenever you attack, that opponent must block
if able then you may negotiate with that
opponent on how to declare their blockers. If
they agree to your terms continue to the damage
step. If they don't, create three 2/2 blue SWAT
creature tokens with menace.
"You are not in control, they are. They are Chris,
they're not listening to you. Now I'm gonna show
them why they should"
