How to play Sejuani in ARAM Mayhem

Sejuani is a solid, middle-of-the-pack pick in ARAM Mayhem on patch 26.21: tier B, #119 of 173 champions, with a 48.1% win rate over 867,428 games.

Sejuani's damage is mixed (61% physical, 32% magic), which makes it awkward for the enemy team to itemize against. It soaks 78,273 damage per game and mitigates another 104,631, so it belongs at the front: start fights and absorb the poke your carries can't.

The Tank build, tank items, is both the most played and the top-ranked path: Heartsteel, Unending Despair and Warmog's Armor, with a 48.6% win rate over 656,297 games. On this build 53% of players skip boots and spend the slot on another item.

The cards that do best on Sejuani are Steel Your Heart, Armored Impact and Goliath. Cards built around health and resistances fill most of the top of its list, followed by ability haste. Most of its S-tier cards are prismatic, so a prismatic offer is often the pick that shapes the game. Skip Marksmage and Heavy Is The Crown when you can: they do worst on Sejuani. A pair to look for: Goliath with Steel Your Heart.

Take Flash and Mark (94% of players). Max W (Winter's Wrath) first, then Q, then E.
