The 6 win % varies a lot. Because of how ofetn you won't get a card you have 4 copies of, or even 8.
Another one is the playstyle. The actual point to this deck is to win, and the Fractal'd vampires achieve this. The Pests are more of a stepping stone up to that, and it's a lot better to have a field full of vampires than of Pests. Remember that, and Fractal Vamps>Pests when you can.
All gathered stats are fairly worthless, since it'd take ~10,000 matches to get an accurate %.
