Kindred vs Master Yi

Hunt the targets of Mark of the Kindred (passive), jungle monsters included: each successful hunt empowers your basic spells, and every 4 hunts, your range increases.

Activate Wolf's Frenzy (W), then fight inside its zone: Dance of Arrows (Q) has a much shorter cooldown there.

Cast Mounting Dread (E), then land three autos on the same target: the third sends Wolf, who strikes based on their missing health.

Cast Lamb's Respite (R) to save your team or deny an objective: nothing inside the zone can die, allies, enemies and monsters alike.

Against Highlander (R), don't run alone: regroup with your team, because he gains speed and ignores slows.

If you have CC other than a slow, land it right after Alpha Strike (Q): during the strike, he's untargetable, and Highlander (R) ignores slows.

If you have CC, interrupt Meditate (W): he channels it to heal, more at low health, and to reduce the damage he takes.

Put pressure on his jungle early on: Master Yi is strongest once he has his items, and each stolen camp delays him.
