Farming
3.3Mordekaiser

Damage

660Sejuani
Mordekaiser heavily out-damages Sejuani by 280 DMG/min, dominating both short trades and all-in fights.

Sejuani provides 0.4 seconds more crowd control per minute than Mordekaiser, offering better gank setup potential and slightly more team fight utility. This CC advantage helps Sejuani coordinate with their jungler and control the pace of skirmishes.
Sustain
1,829Mordekaiser
2,148Sejuani
