Mordekaiser should control the lane by forcing extended trades where his passive and (Q) isolated damage excel against Tahm Kench's low mobility and shield reliance.
Prioritize denying Tahm Kench a passive lane by using (E) pull to prevent him from stacking his passive and forcing him to fight inside your passive range.
This is a control vs survive matchup where Mordekaiser must leverage isolation and extended trades to outscale Tahm Kench's durability and sustain.
Trading pattern
Start trades by threatening or landing (E) to pull Tahm Kench into your range, then hit isolated (Q) for maximum damage.
Extend trades only when your passive shield is active and (W) shield value is stored to outlast Tahm Kench's short trade pattern.
Avoid trading when (E) is on cooldown or Tahm Kench has full passive stacks ready to stun with (Q).
Danger windows
Be cautious when Tahm Kench reaches three passive stacks as his next (Q) can stun and set up lethal trades.
Avoid extended trades without your (W) shield active to prevent Tahm Kench from converting damage into healing.
Respect (R) cooldown as he can remove you from fights or punish overextensions.
Early game
Use early waves to position for (E) pulls and threaten isolated (Q) damage to pressure Tahm Kench before he builds passive stacks.
Avoid walking forward without (E) ready to prevent giving Tahm Kench free passive stacks and (Q) stuns.
Focus on slow melee trades that keep Tahm Kench in your passive zone and limit his ability to heal with (E).
Power spikes
At level 6, use (R) to isolate Tahm Kench and force a duel where his low mobility and inability to kite give you a strong advantage.
After your first AP bruiser item, force longer trades to maintain passive uptime and pressure Tahm Kench's limited sustain.
Respect Tahm Kench's level 6 (R) window by avoiding overcommitment and preparing to disengage if he attempts to isolate you.
Win conditions
Use wave control and (E) pull pressure to force Tahm Kench into extended trades where your passive and (Q) isolated damage dominate.
At level 6, look for opportunities to use (R) to isolate Tahm Kench and secure kills or force him out of lane.
Maintain passive shield uptime and item power spikes to win sustained duels, denying Tahm Kench the chance to scale or survive through short trades.
