Setup with 2 handlers (1, 2) and 1 isolated cutter (3) at the front of the end zone. These are the 3 active players for the start of this player. The other 4 players (4, 5, 6, 7) are stacked at the very back of the end zone.
The iso makes a first cut to try to get free for a goal.
If it's not on, the dump is engaged and they make the cut of their choice.
If that's covered as well, the iso does a fill cut so the disc can be safely reset.
The 3 players continue playing together trying to create a goal, using all the space being create by the deep stack.
The priority for the players in the stack is to leave as much space as possible for the 3 active players. However, there are 3 situations where a player from the stack can look to get involved...
ONE: If one of the 3 active players clears out of the play, they'll join the stack and the front of stack becomes active.
TWO: If a defender of a player in the stack starts poaching, the player they're supposed to be marking needs to get involved and either pull their player back to them, or get the disc.
THREE: If one of the active players gets the disc in a power position, and the other 2 are well out of position, the front of stack can offer a quick cut to see if they can get a goal out of it.
