Malzahar should focus on controlling the wave and maintaining lane pressure to prevent Mordekaiser from setting up slow extended trades.
This is a control vs teamfight matchup where Malzahar must manage wave state and avoid giving Mordekaiser passive lane moments to leverage his isolation and sustain.
Trading pattern
Push with (E) and Voidlings, then threaten trades with (Q) silence when Mordekaiser steps forward.
Punish Mordekaiser when he misses (E) by stepping forward to pressure or force short trades.
Avoid extended trades when Mordekaiser's passive shield is active and hold (R) for confirmed lockdown after wave pressure.
Danger windows
Be cautious when (E) pull is available as it sets up his isolated (Q) and passive damage.
Avoid fighting inside Mordekaiser's passive shield range where his sustained damage and healing from (W) are strong.
Respect (R) isolation window, especially if he has health or item advantage, as it forces a duel without outside help.
Early game
Use (E) and Voidlings to push early waves quickly and deny Mordekaiser the chance to safely farm under tower.
Avoid predictable push patterns that allow Mordekaiser to punish your Voidlings with area damage.
Respect (E) pull threat by keeping spacing to avoid being isolated early.
Power spikes
At level 6, track your (R) availability and use it for verified all-ins or picks rather than forcing blind engages.
After your first mana/AP item, increase wave pressure and trade confidence while respecting Mordekaiser's extended trade threat.
Respect Mordekaiser's level 6 (R) isolation and his first AP bruiser item power spike by avoiding extended trades and holding defensive tools.
Win conditions
Keep the wave pushed permanently to deny Mordekaiser slow extended trades and reduce his isolation threat.
Use your (R) suppression to pick Mordekaiser or force him to play cautiously, enabling map presence.
Control lane pressure and wave state to set up objective plays and teamfights where your lockdown and push excel.
