Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillBoth level 1s are weak — you have only Obliterate, he has only Leap Strike — so farm and set up your level 2 rather than fighting into nothing; call it Skill.
Level 2MordekaiserQ + W online means your Obliterate (which Counter Strike can't dodge) plus a banked Indestructible shield out-trade a Jax whose Counter Strike can't fully charge yet — Mordekaiser's window.
Level 3Even / skillThrough 4-5 your Darkness Rise aura keeps trades close, but a single Counter Strike dodge flips any of them — it's a coin-flip you bait, so call it Skill.
Levels 4-5MordekaiserRealm of Death banishes Jax 1v1 where he can't Leap Strike to tower, steals his stats, and an even-or-ahead Morde wins the box — Mordekaiser's stage.
Level 6JaxJax's Trinity Force / BotRK first item lets his on-hit auto-DPS out-grind your W sustain while a now-chargeable Counter Strike out-trades you — Jax's spike.
First itemJaxAt his second item Grandmaster's Might stacks armor and magic resist and doubles his on-hit, out-scaling your flat damage — Jax pulls ahead.
Two+ itemsJaxLate, his fully-charged Counter Strike stun hard-counters your dash-less all-in and his itemized 1v1 beats yours — play to peel him with R, not duel; Jax owns it.

Early game (levels 1–5)

Both level 1s are middling — you have only Obliterate, he has only Leap Strike — so farm with the tip of your Q and don't hand him a Leap Strike reset off a low minion. Your real window is levels 2-3: once you have Q (Obliterate) and W (Indestructible) you out-trade him, because his only commitment is Leap Strike and a Counter Strike that can't fully charge yet. The rule that decides every trade: Counter Strike (E) dodges your autos and turret shots but NOT your Obliterate, so lead with Q into a raised Counter Strike, then auto only after it expires. If you walk in autoing while it's up, you eat the stun and he gets a free Leap Strike on top.
