Mordekaiser aims to control the lane by forcing extended melee trades where his passive and (W) shield advantage outlast Gangplank's poke and barrel zoning.
Prioritize denying Gangplank a safe scaling lane by maintaining wave pressure and threatening (E) pulls to prevent barrel setups.
This is a control versus scale matchup where Mordekaiser must leverage his isolation and sustained damage to disrupt Gangplank's scaling.
Trading pattern
Initiate trades by threatening (E) to pull Gangplank into melee range, then hit isolated (Q) and keep passive damage ticking.
Avoid starting fights when (E) is on cooldown or when Gangplank has barrels primed, as this reduces your engage safety.
Extend trades only when your (W) shield is charged or (R) can isolate Gangplank, forcing him to fight without barrel support or cleanse.
Danger windows
Be cautious when Gangplank has barrels primed and (W) ready, as he can zone and cleanse your engage attempts.
Avoid extended trades if you miss (E), as your threat and damage output drop significantly.
Watch for (R) global slow during skirmishes, which can hinder your ability to isolate or escape.
Early game
Use early waves to position aggressively for (E) pulls, aiming to isolate Gangplank for (Q) damage and passive ticks.
Avoid walking forward without (E) ready to prevent being poked down by (Q) and barrel chains.
Before level 6, focus on wave control to keep Gangplank within pull range and avoid extended poke without passive active.
Power spikes
At level 6, use (R) to isolate Gangplank and force duels he cannot kite; engage only after landing or threatening (E).
After your first AP bruiser item, force longer trades where your sustained damage and (W) shield outvalue Gangplank's poke.
Respect Gangplank's level 6 (R) global slow and barrel scaling; avoid extended fights when barrels are set and (W) is available to cleanse your pull.
Win conditions
Use wave control and (E) pull pressure to force Gangplank into unfavorable extended trades and isolate him with (R).
Maintain passive damage uptime and (W) shield to win sustained melee fights and deny Gangplank's barrel setups.
Capitalize on (R) isolation to remove Gangplank's cleanse and barrel support, securing kills or forcing him out of lane control.
