Pokefan and Vulpix Yolk win this thread, with an overwhelming majority.
While I agree that Sableye can make a duel quite imbalanced if the opponent gets a great start...oh yeah, that's right, a great start. That isn't always possible. I honestly think, personally, that the problem with this whole thing is either Overeager, Overconfident, or the new B/W rules set: it's one of those three. Remove or restrict any one of those three, and problem solved. (This is just my opinion, however.) Sablelock I don't have as much of a problem with, as the strategy behind it is actually pretty intriguing.
But that's no reason to complain about this deck, is there? If something will be done, hooray; if not, we're losing Sableye in 4 months anyway, so suck it up.
