Why Fizz is favored

Fizz's Playful / Trickster (E) can avoid Breath of Light (Q), and Chum the Waters (R) can knock Aurelion Sol out of its channel while setting up Fizz's burst. Aurelion Sol players describe Fizz as a matchup they need to survive under tower until they scale.

How to play as Fizz

If Aurelion Sol is holding a freeze just outside his tower, use Urchin Strike (Q) to trade only when Playful / Trickster (E) is ready to hop back out of tower range. (Unverified: no source confirms this note.)

When Aurelion Sol commits to channeling Breath of Light (Q), land Chum the Waters (R) to interrupt the channel and start your all-in.

Playful / Trickster (E) makes Fizz untargetable during its hop, letting him avoid Breath of Light (Q); Chum the Waters (R) knocks up and can interrupt Aurelion Sol's channel.

How to play as Aurelion Sol

Hold the wave just outside your tower and use Singularity (E) to preserve the freeze; if Fizz uses Urchin Strike (Q) to reach you, he enters tower range, so do not chase after he hops away with E.
