Kayn

Kayn is an AD assassin in the jungle, and on patch 16.11 they grade out as a top-tier pick — a 52.6% win rate, 7.8% pick rate, 90,797 ranked games sampled. On the power curve, Kayn is a scaling champion: comparatively weak early, but one of the strongest picks on the map once core items come online — so the plan is to survive the laning phase and take the game over late.

How Kayn wins: roaming out of lane to snowball the rest of the map, and grouped 5-v-5 teamfights, where Kayn tips the fight. The kit grades 8/10 roaming, 7/10 teamfighting, 7/10 split-push. Play around where Kayn is thin, siege and disengage (2/10, 2/10), and the enemy loses their angle.

The most-played core build is Voltaic Cyclosword, Black Cleaver, Death's Dance, which holds a 54.9% win rate across 2,605 games this patch. Pick the enemy team to adapt each item slot to the specific matchup.

The matchup to respect is Katarina, where Kayn sits at just 40.1%, the lane swings the other way into Mel (61.8%), and on the team side, Kayn gains the most from a Zac (+13.5% pair win rate).
