This matchup is a control versus teamfight scenario where Aurora aims to use burst and mobility to disrupt Mordekaiser's scaling and teamfight presence.
Trading pattern

Avoid trading right after using (W) since you lose your quick escape tool and Mordekaiser can punish you.

Danger windows
Be cautious when Mordekaiser has (E) ready to pull you into his passive range and extended trades.

Avoid overextending after using (W) since you lack quick escape and Mordekaiser can punish with his sustained damage.
Early game
Use early levels to farm safely and avoid getting pulled by (E), as missing early trades can snowball against you.
Avoid extended trades before your first item spike to reduce risk from Mordekaiser's passive and shield sustain.
Track (E) cooldown to punish missed pulls with quick (Q)+(E) trades and repositioning.
Power spikes
At level 6, use your (R) to create pick or escape opportunities and avoid committing blindly into (R) isolation.
After completing your first AP burst item, increase pressure on waves and trades, forcing Mordekaiser into unfavorable fights.
Respect Mordekaiser's level 6 (R) and first AP bruiser item spikes by holding mobility and defensive cooldowns for his all-in windows.
Win conditions
Use your mobility and burst to pick off Mordekaiser when his (E) is on cooldown and before he reaches key item spikes.
Deny Mordekaiser a slow, extended trade lane by applying pressure after your first item and level 6 ultimate.
Leverage your teamfight disruption and flank pressure to outmaneuver Mordekaiser in mid to late game engagements.
