Based on 7 recent matches analyzed, Karthus wins with a 57.1% win rate compared to Mordekaiser's 42.9%, giving Karthus a 14.3 percentage point advantage. Game phase dynamics play a critical role here: Karthus controls the early laning stage, but Mordekaiser outscales as the game goes longer. The matchup shifts dramatically depending on game length — Karthus needs to press advantages before Mordekaiser reaches their power spikes, while Mordekaiser should focus on safe farming and hitting key item breakpoints.
