@bucky: Cheating is not any easier in a percentage tourney, and we haven't had any more trouble than with the simplest of rules. That's why we run on an honour system and spectate games. In fact, common game expressions are usually more troublesome for newbies. If we suddenly start having big problems with it, we'll certainly use a better system. Until then, there's no basis for complaint.
However, I usually stay away from percentages and use fractions instead. Tends to be less confusing.
Oh, and we won't allow Shards yet since they're hard to get. Eventually though, we'll have a tourney for the recently released cards, in which Shards will be allowed. There's a second reason for that tourney concept, and that's introducing Shards into organized PvP to see how they will fit in the metagame regarding balance.
Also, thanks for the tables, Vineroz and makapse :>
