Why Eyeball Collection
Eyeball Collection is all about fighting from the get-go and getting takedowns to scale into the mid-game.
Why Treasure Hunter
Because Kayn likes to duel and spam his abilities, Ravenous Hunter provides a lot of extra healing in those fights. It also pairs nicely with Rhaast's passive.

Kayn's farly large AoE on [Q] and [W] allow you to hit multiple targets in teamfights, picking up assist/kills and grants you massive healing from Triumph in teamfights/skirmishes.
WhyCoup de Grace
Coup De Grace pairs well with Kayn natural assassin tendencies, and can greatly improve the damage of your [R] when looking to finish off a target.
