I had a random idea, and random ideas can range from awesome to utter crap.

Anyways, what do you make of this tournament variant?

After each round, instead of sorting your cards back up, you instead make a new deck from your Draw Pile, Hand, Units you control, Magic Pile, and Discard Pile, and use that new deck on your next round.

I'm thinking with theft etc. this will only be useful for VASSAL games or the like, but what are your thoughts?
