Irelia should use her high mobility and wave control to pressure Mordekaiser and deny him safe scaling opportunities.
This matchup is a snowball-oriented lane where Irelia wants to leverage wave setups and passive stacks to force extended all-ins and side-lane pressure.
Trading pattern
Stack passive and use low-health minions for (Q) resets to extend trades around (E) stuns or (R) marks.
Punish Mordekaiser after he misses (E) pull or uses (W) shield, as his engage threat and sustain are lower.
Avoid committing with (Q) forward without a reset path to prevent being caught by his pull or extended damage.
Danger windows
Respect (E) pull as it sets up his isolated (Q) damage and extended trades.
Be cautious during Mordekaiser's level 6 (R) realm isolation, especially if he has health or item advantage.
Avoid extended trades when (W) shield is fully charged, as he can convert it into healing.
Early game
Use level 2 power spike with (Q) and (E) to stun and reset trades when Mordekaiser is vulnerable.
Avoid fighting without passive stacks or reset paths since Mordekaiser can punish poor engages.
Keep the wave in states that allow (Q) resets to maintain lane pressure and threaten all-ins before level 6.
Power spikes
At level 2, use (Q) and (E) combo to secure early trades and force Mordekaiser to respect your engage.
At level 6, leverage (R) to mark and slow Mordekaiser, enabling stronger all-ins and harder retreats.
After completing your first fighter item, increase pressure on waves and side-lane trades while tracking Mordekaiser's cooldowns.
Win conditions
Use wave control to maintain passive stacks and create (Q) reset paths for extended all-ins before Mordekaiser can safely trade.
Punish missed (E) pulls and force fights when Mordekaiser's defensive cooldowns are down.
Reach level 6 and first item power spikes to pressure Mordekaiser aggressively, then convert kills into side-lane pressure and skirmishes.
