Based on 5 recent matches analyzed, Olaf wins with a 60.0% win rate compared to Cassiopeia's 40.0%, giving Olaf a 20.0 percentage point advantage. Game phase dynamics play a critical role here: Olaf controls the early laning stage, but Cassiopeia outscales as the game goes longer. The matchup shifts dramatically depending on game length — Olaf needs to press advantages before Cassiopeia reaches their power spikes, while Cassiopeia should focus on safe farming and hitting key item breakpoints.
