Hmmm... I suppose I'll get on beautifying it now, lol. Lots of possitive feedback.
So... I have no idea how to do the scoring. Kobi's suggestion seems to be the best atm. But I want it to be a Best of 5. Otherwise the main point of the idea could play a minimal role.
And about 1 deck becoming too powerful, that's part of the strategy. Using marks that you wouldn't normally use to make your opponents have weaker decks. I don't see it becoming too much of an issue, but I suppose it's something to keep in mind. If it DOES become a problem, maybe we could tweak the rules a bit.
So anyway... prepare yourself for beautification! (when I get around to it that is...)
