Favour timeline — who owns each window

StageFavouredWhy
Level 1JayceLevel 1 is mine — cannon-form Shock Blast through the Acceleration Gate out-ranges Morde and he has no Indestructible shield or ramped Darkness Rise aura yet to trade back.
Level 2Even / skillIt's even at 2 — he now has Q and W to bank a shield against my poke, but I still gate-Q safely from cannon range, so neither of us commits.
Level 3MordekaiserLevel 3 is his — Death's Grasp plus Obliterate plus a banked Indestructible drags me off the gate into his Q and the Darkness Rise aura out-grinds my Shock Blast chip.
Levels 4-5Even / skillSkill window through 4-5 — I poke in cannon but his safe E-into-Obliterate-into-Indestructible trade keeps the lane knife-edge whenever I'm caught in range.
Level 6MordekaiserLevel 6 is his spike — Realm of Death banishes me into a 1v1 where my kite-range and gate poke are useless and he steals my AP and HP on the kill.
First itemMordekaiserFirst AP item is his — it makes the E-into-Obliterate-into-R all-in lethal, and Indestructible heals back my poke faster than I can re-stack the gate-Q.
Two+ itemsEven / skillEven at 2+ items — I keep stance-swap kite and burst and a fed Jayce chunks him, but his R is still a clean pick on me, so the duel is a coinflip on execution.

Early game (levels 1–5)

Levels 1-2 are mine and I have to cash them in. My cannon-form Shock Blast fired through the Acceleration Gate out-ranges everything Morde has, and with no Indestructible banked and his Darkness Rise aura not yet ramped he just eats the chip — gate-Q his step-ups and build a health lead for plates. The danger is level 3: the second he has Obliterate plus Indestructible plus Death's Grasp, his E drags me off the gate and into his Q, and once Darkness Rise is grinding me his shield-heal out-trades my poke. So poke from max range, never stand inside his E pull, and keep hammer-form Thundering Blow up to knock him back if he commits.
