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