Hey guys, ItsDefiance here, this is my first build ever, and this is one I use regularly, and I think is very good. Now yes, I am a bronze III player, but I think my Fizz is deserving more than bronze III. Fizz is an AP assassin that has very high mobility. He can come into a fight, pick out the priorities, and get out before the opposing team has time to think about what happened. This guide is simple, yet extremely effective.

Pros

Fizz has extremely high mobility ( when abilities are off cooldown )
He is, in my opinion, one of the best assassins in game.
Fizz also has a extremely high burst combo. If executed correctly, It should kill the enemy ADC at level 13.
He's a fish! Who doesn't like fish?
Fizz's E negates almost every ability, including ultimate's like Cassiopiea and Katarina.
AoE ultimate
Counters pretty much EVERY AP MID!

Cons

Extremely squishy early game.
E has a long cooldown.
If you waste the E at the wrong time, you're screwed.
A very single priority target champion ( Kind of hard to kill more than one person when you engage in a teamfight after your burn everything on their adc. )
