Favour timeline — who owns each window

StageFavouredWhy
Level 1YasuoYasuo is the level-1 aggressor: Steel Tempest out-ranges your Null Sphere and his Windwall can fully block your only poke spell.
Level 2YasuoHis Q poke plus E dash-through-minions let him chip you freely while your shallow early mana pool can't sustain a Null Sphere trade-war.
Level 3Even / skillAround 4-5 it evens out: Nether Blade mana and a maxed Null Sphere let you farm through his poke and reach 6 without dying to one combo.
Levels 4-5KassadinRiftwalk lets you blink out of his E into third-Q knockup before Last Breath connects, or blink in to punish his E cooldown.
Level 6KassadinRod of Ages stall plus Riftwalk ability haste lets you blink-trade on his Steel Tempest downtime and stop bleeding pressure to him.
First itemKassadinYour post-6 mobility and shield turn the lane: you control engage timing on his cooldowns where he controlled the early poke.
Two+ itemsYasuoOnce Yasuo hits two crit items, his Infinity Edge DPS, flow shield, and Windwall outscale you in any extended duel, so that window is his.

Early game (levels 1–5)

Neither of you blows the other up at level 1, but Yasuo is the early aggressor here. His Steel Tempest (Q) out-ranges your Null Sphere, and once he can E through the wave he chips you while your Q is mana-hungry and on a long cooldown, so don't trade orbs you can't afford. His Windwall (W) eats your Null Sphere outright, so never throw it into a raised W; wait it out. Farm with Nether Blade autos to bank mana, concede the poke, and just reach 6 healthy.
