Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillLevel 1 is an even mana-and-CS standoff — you have only Winds of War and no engage, but Cassiopeia can't commit either with just Noxious Blast.
Level 2CassiopeiaBy level 2-3 her Twin Fang plus poison ramp out-trade you from outside Justice Punch range, and a Miasma grounds your dash before you reach her.
Level 3CassiopeiaWith Q-W-E up you can all-in, but her poison stacks and Miasma cancel the dash, so she still owns the trade tempo if she plays the grounding well.
Levels 4-5CassiopeiaThrough levels 4-5 her sustained poison DPS and move-speed kite beat your cooldown-reliant combo unless she wastes Miasma early.
Level 6CassiopeiaStanding still in lane, her ranged poison still chunks you faster than you can punish her on even footing, even though your spike is coming at 6.
First itemCassiopeiaAt 2+ items her DPS power spike and a single Miasma to ground Justice Punch zone your engage completely, keeping the poke war firmly hers.
Two+ itemsGalioLevel 6 is the verdict: Hero's Entrance lets you ignore the poke war entirely and roam to taunt their carry, and your anti-magic Shield of Durand neutralizes exactly the damage she deals — that map and teamfight value is why the lane reads Galio-favoured.

Early game (levels 1–5)

Level 1 is a wash: you have only Winds of War with no engage, and she only has Noxious Blast, so just contest last-hits, dodge the poison clouds, and bank mana for level 3. The first danger window is 2-3 as her poison ramp comes online — she stacks Noxious Blast and chunks you with Twin Fang from outside your Justice Punch range, and a Miasma grounds the dash so you can't punish. The answer is your identity button: channel Shield of Durand into her Twin Fang to gut the magic damage, then look to release the taunt and E in. Don't chase blind into a cloud, but this is a Galio-favoured lane precisely because your W eats exactly the damage she deals.
