Yasuo scales incredibly fast with attack speed boots, Blade of the Ruined King, and just two critical strike items, making him a strong duelist.
His passive shield and Wind Wall (W) enable powerful laning, but he can be countered by defensive items like Randuin's Omen or champions like Malphite.
Capitalize on allied knock-ups for impactful ultimates (R), but be cautious of aggressive dives as poor engages can turn you into a meat shield.
