On offence, try to move the disc quickly, and reposition yourselves to make throws easy.
The cup's aim is to prevent E getting the disc. Therefore, they should avoid chasing the disc and instead drop into the middle of the field when the disc swings.
You can easily alter this drill to match your own zone defence; the same concept applies regardless of the number of players in the cup, or if you're using an arrowhead or other formation.
Feel free to add your own rules; maybe ban (or force!) overheads, add in another defender, etc.
