How to play as Yasuo
Keep Tryndamere off the wave early so he cannot stack Fury; if he spins onto you before level 6 with little Fury while you are in your minion wave, punish the engage.
When Tryndamere starts with Hail of Blades, kite its burst and re-engage after the rune is on cooldown.
Tryndamere's Battle Fury(P) builds as he attacks and increases his critical strike chance, but Bloodlust(Q) consumes Fury to heal; Yasuo's repeated Steel Tempest(Q) poke can pressure him away from the wave before he stacks it.
