Disc is tapped in (B6) faces (B7).
B6 throws the disc dump to B7 (OI flick could be useful here).
B6 takes their defender up-field to create space for a dump. Simultaneously B7 fakes the swing break side...
B7 turns and finds B6 cutting dump to open space, B7 throws to B6....
B7 then strikes diagonally up field into open space, where B6 can hit her
