On the line we'll call the play "Stack [direction], [name] and [2nd name] man-buddy" and possibly a handler to fill in at the front of the stack. So here we have "Stack right, 1 and 2 man-buddy." It's important to get in position as soon as possible and give the handlers time to take free yards.
The man-buddy pair set up similar to a single iso cutter, with some space between them. On the line the two of them should decide who initiates or who goes under/deep.
Here, 1 takes the under option and gets the disc. 2 sets up the next cut
2 comes under and gets the disc from 1. 3 sets up their cut by attacking toward the middle of the field.
3 goes deep.
But they can also come under.
Whether or not the man-buddy(and following cut) works, the offense should clear and flow into a normal vertical stack in the middle of the field similar to side stack.
