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.
Rumble's ultimate can deal a lot of damage if you stay inside the area of effect. When you see the missiles falling, move out of the way as quickly as possible.
Rumble deals almost entirely magic damage. Build some Magic Resistance to reduce his damage.
Watch Rumble's Heat bar carefully. If you see him Overheat, go in for the kill while his skills are disabled.
