LoL Draft Simulator — AI Draft Analyzer with Win Probability

Simulate a professional League of Legends draft pick by pick and ban by ban. After every selection the simulator recalculates each side's win probability using a Bayesian model trained on professional matches from the LCK, LPL, LEC, LCS, CBLOL and LCP, plus international events like MSI and Worlds. The model combines seven signals: champion win rate on the current patch, lane matchup win rate, duo synergy, recent team form, head-to-head history, team Elo and season win rate.

How to use it

Pick a league and patch range, then draft for blue and red side following the real pro pick/ban order. Champion statistics — pick rate, ban rate and win rate in pro play — update as you filter, and the win-probability bar shows how each pick or ban swings the draft. Use it to prepare scrims, review a pro draft, or test counter-pick ideas against real tournament data.
