I built this deck a couple of years ago, when I was showing Dune to my
friends. It's a training deck, using only EOTS cards. It doesn't do
anything well, but you can easily characterize it as a Atreides Spice
Harvesting deck. Despite that, it still won the inaugural PBEM.

Whilst there is a slight leaning towards Battle, it also has
arbitration through Duke Leto, which allows you to do the unexpected
with it (like the Arbitration for Dune which won me the pbem). It
possesses a few disruptive tactics which can help considerably. If you
just concentrate on getting spice, you should do okay.
