Yasuo must pressure Vayne early to deny her safe scaling and avoid giving her room to kite and reposition.
Use your high mobility and wave control to create short trades and all-in windows near minions, preventing Vayne from using her ranged advantage safely.
Trading pattern
Stack (Q) and use (E) to dash through minions, controlling space and forcing Vayne into close range.
Use (W) to block Vayne's key projectiles and engage only when (W) and passive shield are up.
Commit on knockup threat from your second (Q) to enable (R) all-ins, punishing Vayne's fragility and lack of hard disengage.
Danger windows
Respect (E) wall stun and (R) stealth repositioning, which enable her to punish overextensions.
Avoid trading when your (W) shield and passive shield are down, as Vayne's true damage and (E) threaten lethal counters.
Be cautious of Vayne's positioning near walls where she can easily stun you with (E).
Early game
Reach level 2 quickly to unlock (Q) and (E) combo for stronger trades and mobility.
Use minion waves to dash and engage short trades before Vayne can safely retaliate.
Avoid extended fights without (W) shield as Vayne's true damage and (E) stun threaten lethal countertrades.
Power spikes
Level 2 unlocks your (Q)+(E) combo, enabling stronger trades; use this window to pressure Vayne when she is most vulnerable.
Level 6 grants (R) for follow-up on knockups; track this to execute decisive all-ins or disengage safely.
After your first item, increase pressure on waves and trades, forcing Vayne into risky positions before she scales.
Win conditions
Use your mobility and (Q)+(E) combos to deny Vayne safe farming and force short trades near minions.
Exploit windows when (E) is down or (W) shield is up to all-in with knockups and (R) follow-ups.
Snowball early leads by pressuring waves and side lanes to prevent Vayne from reaching her late-game duel power.
