How to play Kai'Sa in ARAM Mayhem

Kai'Sa is a solid, middle-of-the-pack pick in ARAM Mayhem on patch 26.21: tier B, #82 of 173 champions, with a 49.5% win rate over 3,183,874 games. It is also one of the most picked champions, showing up in 14% of games, so expect to see it on both sides.

75% of Kai'Sa's damage to champions is magic, so enemy magic resist is what slows it down. It deals 44,149 damage to champions in an average game, more than most champions, so play to stay alive and keep hitting. It brings almost no crowd control, so it relies on teammates to set up kills. It dies only 9.0 times per game on average, fewer than most.

The AP build, ability power items, is both the most played and the top-ranked path: Luden's Echo, Dusk and Dawn and Shadowflame, with a 49.6% win rate over 1,585,509 games. On this build 64% of players skip boots and spend the slot on another item.

The cards that do best on Kai'Sa are BEES!!!, Ethereal Weapon and Back To Basics. Cards built around ability haste fill most of the top of its list, followed by ability power. Most of its S-tier cards are prismatic, so a prismatic offer is often the pick that shapes the game. Skip Spin Me Right Round and Bread And Butter when you can: they do worst on Kai'Sa. A pair to look for: Back To Basics with BEES!!!.

Take Flash and Ghost (65% of players); Mark is the common alternative. Max W (Void Seeker) first, then Q, then E.
