Mordekaiser is a polarized champion with a high ceiling but a slow, methodical playstyle that often struggles in fast-paced encounters. His strength lies in generating overwhelming board value through the Deathless keyword and infinite revive loops. However, his heavy reliance on specific high-tier relics to bypass a slow early game, combined with significant board space limitations, can make his progression feel cumbersome. While he is exceptionally powerful in adventures tailored for titanic units, he requires careful setup and investment to remain competitive in high-difficulty nightmare scenarios.
Titanic Mana Ramp Build
Utilizes Mordekaiser's Titanic status to provide an extra mana gem at game start, significantly accelerating his arrival on the board.
Reduces his cost based on the number of allies in play, allowing for early deployment while triggering slay effects that Mordekaiser leverages for scaling.
Generates high-cost units upon summoning that are discounted by Mordekaiser's base cost, providing immediate board stabilization and synergy with Shadow Isles or Noxus regions.
Strategy
This is the definitive setup for Mordekaiser. The combination of mana acceleration and cost reduction ensures he can be deployed before the enemy overwhelms the board. Once in play, Mordekaiser uses his revive mechanics to trigger 'on summon' or 'last breath' effects repeatedly, creating a board state that is nearly impossible for the AI to interact with effectively.
Infinite Revive Loop Build
- Essential for reducing cost and enabling the slay triggers necessary to start Mordekaiser's engine.
Provides an extra revive and interacts with Mordekaiser's ability to kill and revive allies, allowing for the duplication of Mordekaiser himself when combined with specific slay effects.
Allows Mordekaiser to absorb the stats and keywords of supported allies, clearing board space while growing into an unstoppable threat with Overwhelm.
Strategy
This build focuses on the 'printing' aspect of Mordekaiser's kit. By using slay spells or the Corrupted Star Fragment on a Mordekaiser that has a revive pending, players can maintain multiple copies of the champion on the board. This stacks his Level 2 drain effect and ensures constant sustain.
Other Relic Options
Increases consistency by ensuring Mordekaiser is drawn early and provides additional copies of his champion spell, which is vital for board control.
A niche defensive option that ensures Mordekaiser summons himself after a delay, though it is often considered slower than direct mana ramp.
Effective for collecting keywords as units die, turning Mordekaiser into a multi-keyword finisher in longer encounters.
While rare relics like Corrupted Star Fragment are functional, Mordekaiser is notably weaker without Disciple of Shadows. Avoid relics that grant protection like Death's Foil, as Mordekaiser actively benefits from his units (and himself) dying to trigger revives.
Constellation
Mordekaiser's constellation is heavily weighted toward his late-game scaling. At base levels, he is hampered by a high mana cost and a starting deck that can feel clunky. Upgrading his stars is essential to provide the stat buffs and keyword generation (specifically Overwhelm) needed to close out games.
Twice Slain
Round Start: If you have the attack token, create a 2 cost Indestructible in hand or if you have one, reduce its cost by 1.
Thrice Born
+1 Starting Mana. When you revive an ally, grant it +2|+0 and Overwhelm.
Twice Slain II
Round Start: Create a 2 cost Indestructible in hand or if you have one, reduce its cost by 1.Review
This is the most critical milestone for basic playability, ensuring that revived units return with enhanced stats and Overwhelm. Without this, Mordekaiser lacks a reliable win condition beyond grinding the opponent down.
Gameplay Tips
- Manage Board Space Aggressively
Mordekaiser's greatest weakness is his tendency to overfill the board. Use slay effects or Corrupted Star Fragment to consume smaller units and make room for revives or high-impact summons from Portal Pals.
- Prioritize the Level 2 Sustain
Mordekaiser's leveled-up form provides significant Nexus health drain on slay. In difficult encounters, prioritize protecting at least one Mordekaiser while using spells to kill your own units, ensuring you stay at full health while depleting the enemy's.
- Leverage the Deathless Keyword
Units with Deathless are the fuel for Mordekaiser’s engine. Use them to block high-attack enemies without fear, as they will return stronger and contribute to Mordekaiser's level-up progress.
- Synergize with Support Champions
Champions who benefit from dying or being revived, such as Viego or Kindred, are exceptional partners. Support champions like Rumble also provide valuable keywords that can be transferred to Mordekaiser via relics.
