Gwen vs Yone

Land 4 autos before Snip Snip! (Q): each auto adds a snip, on top of the first and the last.

Land the center of Snip Snip! (Q): in the center, part of the damage becomes true damage and each snip applies A Thousand Cuts (passive).

Place Hallowed Mist (W) against poke and ranged CC: enemies outside the mist can't target you, except towers.

Cast all three Needlework (R) activations within 6 seconds: the first throws one needle, then three, then five, with growing damage.

Get out of his line after two Mortal Steel (Q) hits: the next one makes him dash forward and knocks the enemies hit into the air.

During Soul Unbound (E), avoid taking hits: when he snaps back, part of all the damage he dealt you is repeated.

If you have ground-targeted CC, place it on the body he left behind: when Soul Unbound (E) ends, he has to return there.

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

In teamfights, don't line up with your allies in front of him: Fate Sealed (R) hits every enemy in a line and knocks them into the air toward him.
