Favour timeline — the windows in Mordekaiser's game plan

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

This is Mordekaiser's own plan; across 665 pooled games the lane is leaning Irelia.

StageFavouredWhy
Level 1Even / skillLevel 1 with only Q and no Darkness Rise aura you have no all-in, and her Bladesurge dash plus future E stun mean a clean skirmish favors neither side — just farm.
Level 2MordekaiserQ + W online: your single-target Obliterate sweetspot and a banked Indestructible shield out-trade her single Q before she has E (Flawless Duet) to punish you.
Level 3MordekaiserWith Q, W and the start of your E and Darkness Rise you win short melee trades that her poke and lone Bladesurge can't sustain through.
Levels 4-5Even / skillYou stay favoured as Darkness Rise grinds extended fights, but Bladesurge resets off any dying minion and heals her back — hence Skill, not yours.
Level 6MordekaiserRealm of Death isolates her from her tower and allies and steals her stats — a near-guaranteed kill with no third party to save her, flipping the lane.
First itemMordekaiserYour Liandry's Torment and Sorcerer's Shoes magic pen make the E-pull-into-aura all-in lethal in the window before her Trinity Force spikes.
Two+ itemsIreliaShe out-scales you: Trinity Force, on-hit item DPS and Q-reset kiting beat your flat HP-stacking late game while you stay gap-closer-less.

How to beat Irelia as Mordekaiser: the early game

"Her Q (Bladesurge) dashes and resets off minions, so she can flicker in to all-in the moment you wind up Obliterate — telegraph your Q and she dashes through it, then E-stuns you mid-trade. Trade back with the start of your combo: land Obliterate at the single-target sweetspot for the bonus damage and a Darkness Rise hit, and bank the damage into Indestructible so her chip doesn't stick. Don't chase a Q she'll just reset off a caster minion — let her overextend into your aura instead, and respect that her Defiant Dance (W) eats your Obliterate burst if she channels it."
