Fizz's spells scale off Ability Power - consider getting items like Zhonya's Hourglass or Banshee's Veil against teams that have high burst threat - and items like Lich Bane or Rabadon's Deathcap if you think you can survive without the Health.
Since Fizz can move through units, find opportunities in lane to walk through minions and apply Seastone Trident's passive - following it up with the ability's active attack after a few seconds.
Fizz's ultimate ability, Chum the Waters, can be aimed at an enemy or towards the area where you think they'll be going.
Make sure to buy items that will evolve at least 1 or 2 of your spells.
Work with your teammates to set up your Ultimate and optimize damage with your passive.
Try to catch enemy carries alone to burst them with Icathian Rain.
