Disc should start on the opposite side of the field to the stack but not too close to the sideline. As an alternative, 7 can start isolated in the space in front of the thrower.
Back of stack (Omega) creates separation...
...and gets the disc (in theory, this can be under or deep). As he gets the disc under, the stack should push deeper.
Continuation is to the new Omega who starts setting up cut as the inactive dump (2) becomes the front of stack and the previous thrower (1) becomes the dump.
Again, 6 can get the disc under or deep. In the case of getting it under, the stack keeps pushing and the dumps keep cycling.
