How to play as Yasuo
Track Annie's Pyromania stacks before dashing in. Wind Wall only helps against her Q projectile, so respect a ready stun from W or R and use the minion wave to approach on your terms.
Wind Wall(W) can stop Annie's Disintegrate(Q) projectile; if her Pyromania stun(Q) is blocked before it hits, the stun is not consumed and remains for her next offensive spell.
Annie's Incinerate(W) and Summon: Tibbers(R) are area effects, not projectiles, so Wind Wall(W) does not block their damage or stun.
How to play as Annie
Use basic attacks to remove Yasuo's Flow shield, and save a stun from W or R for when he commits; both can reach him through Wind Wall.
