Bah, excuses!
I prepared none of my decks (Granted, I did pay a price, but it was only because of my stupidity and probably wouldn't have been fixed had I set my decks up in advance) and still won.
I did also have an advantage, but I think it was balanced by the penalty given to me.
Honestly Blood, it doesn't take all that long to prepare decks at all. Just 5-10 minutes, you should have the cards you need already.
SG will certainly see it as stalling, I know that.
