Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillNeither champion has their full kit and Mordekaiser cannot yet trigger his E-into-Q isolated-bonus combo — farm safely with Q Chain Lash at max range and match his level-one Q poke without committing.
Level 2MordekaiserMordekaiser's W Iron Man shield is already building and his Q isolated bonus rewards any melee exchange — your E is online but his shield absorbs your burst before you can W Kingslayer for meaningful damage.
Level 3MordekaiserHis full E-pull into Q isolated bonus into W-shielded sustain is now live and punishes every extended trade — dodge his E with your own E dash and do not contest him in melee without a health advantage.
Levels 4-5Even / skillBoth kits are fully active but neither has the item power to decisively end the other — trade short, keep your W Kingslayer heal ready, and avoid getting E-pulled near your own tower where his Q isolated bonus hurts most.
Level 6MordekaiserRealm of Death exiles you and steals your stats at the exact moment you have no item sustain to outlast the duel — respect the all-in threat and use E Abduct immediately inside the Realm to burst him before the stat difference widens.
First itemSylasRiftmaker Omnivamp compounds through every W Kingslayer heal in extended trades, flipping the sustain math that favoured him in lane — force repeated brawls now and his W shield can no longer keep pace with your healing.
Two+ itemsSylasTwo AP items make your Hijacked Realm of Death stronger than his original cast and your Riftmaker keeps you healthy through the opening burst — steal his R, exile him, and convert the lead he built in lane into a decisive teamfight win condition.

Early game (levels 1–5)

At level one neither of you has a complete kit, but Mordekaiser's Q slam already punishes you if you walk into his melee range without your E available yet — respect his auto-Q poke and last-hit from max range. His W Iron Man shield ramps off his own ability usage, so even short trades favour him once that shield is up. At level three his E pull comes online and the matchup becomes genuinely dangerous: if he E-pulls you he immediately triggers his Q isolated bonus damage, and you are stuck eating both while his W absorbs your counterplay. Keep the wave slightly pushed so you have room to E-dash through or away from his E pull rather than getting pinned against your own tower wall.
