Both clans can choose their map, and after they will eliminate the maps who weren't played yet. Example:
Maplist:
dm4
dm5
dm6
dm7
dm10
dm13
Dm7 and Dm6 played, +nL/ won the second scrim. They eliminate dm5
dm4
dm10
dm13
left.
After LoVe eliminates 10
dm4
dm13
left.
+nL/ eleminates 13 and so dm4 will be played.
