Favour timeline — the windows in Mordekaiser's game plan

Read from Mordekaiser's seat: which stage windows this plan plays for against Sion.

StageFavouredWhy
Level 1Even / skillYou only have Q and he only wants to charge a knockup — neither has an all-in, so farm and dodge the charged smash.
Level 2MordekaiserQ + W comes online: your single-target Obliterate plus banked W shield out-trades his lone E shield-break poke.
Level 3MordekaiserE-pull into single-target Q stacks Darkness Rise, and your aura grinds him faster than his Soul Furnace shield can soak.
Levels 4-5MordekaiserIn extended trades your aura DPS plus W heal out-sustain his E poke — a tank can't out-damage your melee aura.
Level 6MordekaiserRealm of Death isolates him into a 7-second 1v1 and steals his stats — the worst place for a teamfight-only tank.
First itemMordekaiserLiandry's burn and your E magic pen cut through his stacked HP and Soul Furnace shield, making the all-in lethal.
Two+ itemsEven / skillHe never out-scales you 1v1, but a healthy Sion's charged Q and tank stats become real teamfight engage — close it out first.

How to beat Sion as Mordekaiser: the early game

"\"Level 1 is a wash — you only have Q and Sion just wants to charge a Q knockup and chip you with E, so farm with the cone tip and never stand in a charging smash. From level 2 you take the lane: bait his E poke, then E-pull him into a single-target Q and start stacking Darkness Rise. His W gives a shield plus bonus max HP, but it doesn't recast into a heal like your W does — you win every short trade where you both walk away. Just don't get caught flat-footed by a max-charge Q.\""
