How to play Yuumi in ARAM Mayhem

Yuumi is a strong pick in ARAM Mayhem on patch 26.21: tier A, #35 of 173 champions, with a 51.7% win rate over 683,894 games. Riot rates it 2/10 for difficulty: easy to pick up when it lands on your bench.

84% of Yuumi's damage to champions is magic, so enemy magic resist is what slows it down. It keeps its team alive with 9,838 healing and 13,264 shielding on teammates in an average game; stay behind your frontline and save it for the fights that matter. It dies only 5.3 times per game on average, fewer than most.

The Support build, support items that heal and shield allies, is both the most played and the top-ranked path: Whispering Circlet, Moonstone Renewer and Staff of Flowing Water, with a 53.0% win rate over 437,107 games. On this build 97% of players skip boots and spend the slot on another item.

The cards that do best on Yuumi are Windspeaker's Blessing, Infinite Recursion and Enchanting Butterflies. Cards built around ability haste fill most of the top of its list, followed by healing and shielding allies. Most of its S-tier cards are prismatic, so a prismatic offer is often the pick that shapes the game. Skip Triggered Inferno and Warlock Juicebox when you can: they do worst on Yuumi. A pair to look for: Windspeaker's Blessing with Enchanting Butterflies.

Take Heal and Ignite (48% of players). Max Q (Prowling Projectile) first, then E, then W.
