Xayah vs Sivir

Cast a spell before your autos: with Clean Cuts (passive), they pass through every target in their path and each leave a feather to call back.

Activate Deadly Plumage (W) before a trade: you gain attack speed, each auto fires a second blade, and hitting a champion makes you faster.

Position yourself so that Bladecaller (E) pulls your feathers back through your target: at least 3 feathers have to hit them to root them.

Cast Featherstorm (R) to dodge a decisive spell: you're untargetable for 1.5 seconds, then you leave a line of feathers to call back with Bladecaller (E).

Dodge Boomerang Blade (Q), then its return: it damages on the way out and on the way back, and it costs Sivir a lot of mana.

If you have CC, cast a cheap spell first, or fake a step forward: Spell Shield (E) only blocks one ability, and heals her if it blocks.

Back off when she casts On The Hunt (R): her whole nearby team gains move speed to engage on yours.

Don't leave her alone on a lane for too long: with Ricochet (W), her autos bounce between minions, and your wave, then your tower, fall fast.
