How to play Mordekaiser in ARAM Mayhem

Mordekaiser is a below-average pick in ARAM Mayhem on patch 26.21: tier C, #149 of 173 champions, with a 46.3% win rate over 1,641,661 games.

78% of Mordekaiser's damage to champions is magic, so enemy magic resist is what slows it down. It soaks 64,560 damage per game and mitigates another 86,639, so it belongs at the front: start fights and absorb the poke your carries can't.

The AP build, ability power items, is both the most played and the top-ranked path: Rylai's Crystal Scepter, Riftmaker and Liandry's Torment, with a 47.4% win rate over 583,998 games. For boots, most players buy Mercury's Treads, but Gluttonous Greaves rank higher.

The cards that do best on Mordekaiser are The Boom and the Bass, Take'em Down Down Down and Omni Soul. Cards built around attack speed and on-hit fill most of the top of its list, followed by movement speed. Skip Shrink Ray and Can't Touch This when you can: they do worst on Mordekaiser. A pair to look for: Dual Wield with Hellbent.

Take Flash and Mark (93% of players). Max Q (Obliterate) first, then E, then W.
