Jayce vs Mordekaiser Counter Pick
Matchup Summary
What the Data Means
Jayce is a fighter/marksman hybrid, Mordekaiser a fighter/mage hybrid, and they meet in the Top lane. 984 tracked games on 16.13.1 put Jayce at a 54.2% win rate into Mordekaiser. That is 4.2 points above even, so Mordekaiser is one of the matchups Jayce can lean on.
The exchange usually opens with Thundering Blow / Acceleration Gate (E) or Obliterate (Q). Then it becomes Mercury Cannon / Mercury Hammer against Realm of Death, and the one still holding it sets the terms. Note the resource bars too: Mana versus Shield.
With both sitting in melee range (125 against 175), neither side gets a free poke pattern.
Damage types split — physical from Jayce, magic from Mordekaiser — making that first resistance a real decision. Before items it is 590 HP, 22 armour, 30 MR for Jayce; 645, 37, 32 for Mordekaiser. That 15-point armour gap favours Mordekaiser in the first all-in. Jayce scales to 2443 health by 18 while Mordekaiser reaches 2413.
Jayce is the more demanding of the two to pilot (7/10 versus 4/10), which quietly shapes the win rate. The 984-game sample behind Jayce versus Mordekaiser is data rather than opinion.
