Imperator Furiosa

Start your engines! (If you have no speed, it starts
at 1. It increases once on each of your turns when an opponent loses life. Max speed is 4.)

Whenever you attack, Imperator Furiosa deals 1 damage to each opponent.

Max speed - If a source you control would deal damage to an opponent or a permanent an opponent controls, it deals that much damage plus 1 instead.
