Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillLevel 1 you have one ability and no poison to feed Twin Fang, so his point-and-click passive auto and Winds of War (Q) poke trade evenly until you land a second spell.
Level 2CassiopeiaYour second point across Q/E lets you prime poison and Twin-Fang for damage his slow Q poke and tank base stats cannot answer.
Level 3CassiopeiaA full Q-into-E combo with leveled move-speed kiting out-DPSes his early trade, and you can hold Miasma to ground his E dash before he reaches you.
Levels 4-5CassiopeiaRanks in Q and E chain near-continuous Twin Fangs that shred a pre-MR Galio, who has no sustain and no escape from your poison while grounded.
Level 6CassiopeiaPetrifying Gaze stuns him out of his Hero's Entrance / E-dash all-in — your clean answer to his only engage window, turning his dive into your kill.
First itemCassiopeiaMalignance or early Liandry's plus your leveled passive move speed make you a kiting poke threat he cannot trade back into before he itemizes MR.
Two+ itemsGalioOnce he completes Force of Nation / Abyssal his MR blunts your E and poison while his global R and tankiness take over the map — you stay squishy and fall off, so the late game tilts to him.

Early game (levels 1–5)

Galio is a slow, melee-range AP tank with no early sustain, and you out-poke him from the first level — your Q lays poison, then E (Twin Fang) nukes for bonus damage and refunds most of its cooldown, so you can chain it on him while his Winds of War (Q) and passive-empowered auto do far less. Level 1 is roughly even since you only have one ability up and his point-and-click passive auto trades fine, but the moment you have two points across Q/E you prime-and-Twin-Fang for a real lead. Hold W (Miasma) — its grounding shuts off his E dash (Justice Punch) and his R, so save it to deny his gap-closer rather than burning it as a slow.
