Maps will be chosen by vetoing. The referee will toss a coin to decide who gets to downvote a map first. Then, taking turns, each player will eliminate a map until only three remain. These three maps will be the maps for the Bo3 series. For the finals, only two maps will be eliminated by downvote.
The player who did the first elimination will then pick which of the three remaining maps should be played first, while the other player will pick the one that will be used for Game 2. The remaining map will be played in Game 3. For the finals, the same picking process will be used, but will extend to 5 games instead of 3.
