Fizz Idea unique

Ult could be a activation spell that activates on use and for the next 10 sec fizz AA deals bonus magic damage and marks a enemy champion(would work with Q),if fizz gets 3 stacks on a single target the shark comes and deals aoe dmg like normal.

PLUS: Fizz current W could be another mobility spell with no damage and his E would stay as it is only changing the 2nc cast so that you would have to fall on the location you use the first cast.

Like the idea of fizz cutting his opponent for his shark to eat like a treat.
