Yasuo vs Vladimir

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.

Force him to use Sanguine Pool (W) early in the fight, when it costs him the most health: he can't become untargetable again for 28 to 16 seconds.

Back off after his first two Transfusion (Q) casts: the next one is empowered, hits harder and heals him based on his missing health.

Get ahead early: Vladimir mostly shines later, once he has his items, since Crimson Pact (passive) turns his ability power into health and his bonus health into ability power.

During Hemoplague (R), focus him if you can kill him before the blast, otherwise back off: you take increased damage until then, and the blast heals him per champion hit.

If you have Grievous Wounds, apply it to him: Transfusion (Q), Sanguine Pool (W) and Hemoplague (R) all heal him.
