Viktor is a scaling control mage who must manage wave control and avoid giving Yasuo easy all-in windows.
Maintain medium lane pressure to prevent Yasuo from freely using minions for mobility and trades.
Focus on scaling through item upgrades to dominate teamfights and control space later in the game.
Trading pattern
Trade by poking with (E) and shielding with (Q), keeping (W) to slow and stun if Yasuo commits.
Punish Yasuo when his (W) is down by stepping forward to land reliable (E) poke and zone control.
Avoid using (W) solely for waveclear as it leaves you vulnerable to Yasuo's high mobility all-ins.
Danger windows
Yasuo is most dangerous at level 2 with (Q)+(E) mobility; avoid giving him minion waves and space to engage.
Be cautious when your (W) is down as you lose key disengage and crowd control against Yasuo's all-ins.
Track Yasuo's ultimate availability and hold defensive cooldowns to survive his knockup and follow-up damage.
Early game
Use level 1-3 to safely farm and poke with (E) while keeping (W) ready to disengage from Yasuo's early mobility combos.
Avoid extended trades before your first item; instead, focus on spacing and wave management to deny Yasuo clean engage setups.
Respect Yasuo's level 2 burst potential and avoid giving him minion waves to dash through for aggressive trades.
Power spikes
Level 6 (R) unlock grants Viktor strong zone control and all-in potential; use it for picks or defensive resets.
First completed mage item and ability evolutions significantly increase Viktor's poke and trade reliability; pressure Yasuo more confidently after this.
Respect Yasuo's level 2 combo and level 6 (R) for knockup follow-ups; avoid overextending during these windows.
Win conditions
Scale safely through farming and item upgrades to outdamage Yasuo in teamfights and control zones with evolved abilities.
Use (W) zone control to punish Yasuo's reliance on minion waves for mobility by controlling wave states.
Exploit Yasuo's vulnerability when his (W) and passive shield are down by stepping forward for trades and wave pressure.
