Mordekaiser should control the lane by using (E) to pull Olaf into extended trades where his passive and (Q) isolated damage excel.
Focus on denying Olaf a passive lane and avoid giving him easy all-in windows by respecting his (Q) slow and (R) immunity.
This is a control vs snowball matchup where Mordekaiser aims to outscale Olaf through sustained AP damage and isolation duels.
Trading pattern
Start trades by threatening or landing (E) to pull Olaf into your passive range, then hit isolated (Q) for max damage.
Extend trades only when your passive is active and (W) shield is stocked to outlast Olaf's true damage and lifesteal.
Avoid trading if (E) misses or Olaf has (R) active and can ignore crowd control; wait for cooldown windows to punish.
Danger windows
Olaf is most dangerous when he lands (Q) and picks up axes to slow and chase you; avoid extended fights without (E) ready.
Be cautious when Olaf activates (R), as he ignores your crowd control and can force all-ins; disengage or wait for (R) to expire.
Missed (E) pulls leave you vulnerable to Olaf's true damage (E) and extended trades; play defensively until (E) is available again.
Early game
Use early levels to farm safely and threaten (E) pulls to zone Olaf and prevent him from freely picking up axes.
Avoid extended trades before level 6 if (E) is on cooldown or missed, as Olaf's early pressure and (Q) slow are strong.
Build up (W) shield value by trading only when you can maintain passive damage and avoid Olaf's true damage (E).
Power spikes
At level 6, use (R) to isolate Olaf and force a duel where your sustained damage and passive shine; avoid using (R) if Olaf can kite or disengage.
After your first AP bruiser item, force longer trades leveraging your improved durability and damage to outlast Olaf's burst and sustain.
Respect Olaf's level 6 (R) spike when he gains crowd control immunity; avoid committing unless you can keep him inside your passive zone.
Win conditions
Use wave control and (E) threat to force Olaf into extended trades where your passive and (Q) isolated hits dominate.
At level 6, isolate Olaf with (R) when you have health or item advantage to secure kills or force summoners.
Maintain (W) shield uptime and force Olaf into fights where he cannot disengage or kite, leveraging your sustained AP damage and isolation to win duels.
