Vladimir vs Yasuo

After two Transfusion (Q) casts, the next one is empowered for a few seconds: save it for a trade, since it hits harder and heals you based on your missing health.

Last-hit minions with Transfusion (Q) until your items come in: it deals damage before healing you, and costs you nothing.

Charge Tides of Blood (E) for at least 1 second before releasing: the missiles then also slow, and their damage grows with the charge.

Save Sanguine Pool (W) to dodge CC or a burst: for 2 seconds, you're untargetable. It costs you part of your current health.

Cast Hemoplague (R) before your burst: infected enemies take increased damage from all sources, then the blast heals you for each champion hit.

Hit him with a cheap attack to trigger the Way of the Wanderer (passive) shield, then start the real trade: otherwise, it absorbs your best damage.

If you have projectiles, save them for after Wind Wall (W): it blocks them all for 4 seconds, on a 25 to 17 second cooldown. Other spells go through it.

Don't stand right behind your minions: each one gives him a target for Sweeping Blade (E), and he gets closer to you with every dash.

Get out of the line of his whirlwind, the third Steel Tempest (Q): without a knock-up, he can't cast Last Breath (R).

Judge his threat by his crit items more than his level: Way of the Wanderer (passive) raises his critical strike chance, so each crit item does more for him.
