It's definitely biased. Sometimes this is good, sometimes it's bad. I did author the devourer bias topic, afterall, so it's kinda obvious what my opinion is. But like I said, it can be good. Today I had about seven games in a row where I won a card from the second spin, two of which I won all three spins and another of which I won two of the spins. I mean, no one is that lucky, but if I am, I'm headed for Vegas in a few months when I'm 21. Oh, and I was recently testing a bunch of decks for the tournament yesterday, and one said deck used two arsenics. In 90% of the games they were either both very close to the bottom, or very close to the top. I mean either I drew them both at the start of the game or I didn't draw one until I had fewer than 10 cards left. This leads me to believe that cards next tou each other in your deck are often close together... It could be tested by taking a deck of 30 different cards and recording your drawing order over 100 games. It wouldn't take too long either if you just use two accounts and duel yourself... You could do 2 decks at once. A good deck would probably be 6 other cards and then 2 cards from each element.
