Favour timeline — the windows in Gnar's game plan

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

StageFavouredWhy
Level 1GnarMini's ranged autos plus a single Boomerang win the first trade — Morde has no dash to punish you and can only eat the poke.
Level 2MordekaiserHis W shield makes the return trade safe, and stepping in for the Hyper proc lets his E pull and isolated Q slam your fragile Mini body.
Level 3MordekaiserAt 3 his full E-pull into isolated Q with W shield up out-trades a squishy Mini Gnar who overstays inside his range.
Levels 4-5GnarWith Rage banked your Mega Wallop stuns him even through his W shield and a wall-pinned GNAR! flattens his dash-less body for the kill.
Level 6MordekaiserRealm of Death drags you into a stat-siphoning death-realm 1v1 — caught in Mini with no Mega bulk or wall, you lose that duel.
First itemEven / skillIt is pure form RNG: Mega-up you wall-combo him, Mega-down he ults you, so the window is a coin-flip on your Rage timer.
Two+ itemsGnarYour wall-ult and front-to-back Hyper kiting peel him off the carry, wasting his single-target R and reclaiming the teamfight.

How to beat Mordekaiser as Gnar: the early game

Level 1-2 is mine: Mini's ranged autos plus a Boomerang let me poke a dash-less Morde who simply cannot trade back, so I chip him and step out past his Q range. But the second I walk in for the Hyper third-hit proc, his E can drag me in, and at 2-3 his Q lands its isolated bonus damage on my squishy Mini body while his W shields the counter-trade — that flips short range hard to him. Hit him at distance, never sit inside his E.
