Why this duo works
Chum the Waters (Fizz R) slows and then knocks up a target, while Hounds' Pursuit (Naafiri R) lets Naafiri and her pack close onto a champion. Layering those entry tools on one isolated target gives the duo a focused burst window, with Fizz's magic damage and Naafiri's physical damage.
Playing the duo
Fizz R delays its knock-up after slowing a marked target, and Naafiri R sends Naafiri and her pack toward a champion; the two abilities can layer control and damage on the same target.
How to play as Naafiri
Use Naafiri R on the same isolated target Fizz has caught, and time the follow-up so the target cannot simply walk away after the shark's control ends.
How to play as Fizz
When Naafiri is in range to follow, use Fizz R to start the catch before spending Fizz Q or Fizz E; the slow helps her line up her entry.
