Yasuo vs Annie

Hit twice with Steel Tempest (Q), on minions if needed, to charge the whirlwind. Cast it during Sweeping Blade (E): the strike becomes a circle.

Keep moving before taking a trade: Way of the Wanderer (passive) builds your shield while you move, and it triggers on the first hit you take.

Chain Sweeping Blade (E) on different targets to reposition or dodge: each target has its own cooldown, so the spell comes back almost instantly.

Save Wind Wall (W) for a projectile that decides the teamfight, like Jinx's ult, rather than for poke: it blocks for 4 seconds, on a 25 to 17 second cooldown.

Watch for your allies' knock-ups: Last Breath (R) can be cast on any airborne champion, whether the knock-up comes from your whirlwind or Malphite's ult.

Back off when Pyromania (passive) is ready: after 4 spells, her next offensive spell stuns you. She has it ready at the start and every time she respawns.

If your range is longer than hers, poke her from outside it: her autos and Disintegrate (Q) reach 625, Incinerate (W) 600.

Once she hits level 6, stay well outside her range when her stun is ready: with Flash, Summon: Tibbers (R) can land on you from much farther away.

Take the teamfight once Tibbers has been cast and is gone, because Summon: Tibbers (R) has a 130 to 100 second cooldown and is her biggest source of damage.
