Ok, I read about this on the Net in a few places. You take your opponent's deck, and pile shuffle using 3 piles. If your opponent has stacked their deck "spell, spell, land", this screws them. Is this cheating? I've heard it called cheating each time it was mentioned. However, it doesn't feel wrong to me...if your opponent was cheating, then they deserve it, and if not, it's a fair way to shuffle. BUT, If you really suspect they stacked their deck, you call a judge. Since, in this case, it seems likely that it is cheating to do a 3-pile. So, the idea of just doing that shuffle to each opponent, is that considered cheating? I've never done this in any sort of game, but it sounds fair enough. So many times, I know my opponents have tried to cheat me but I stop them. How many times do I never realize it and get screwed? I try to shuffle my own deck about 6-7 times b/w games, 10 b/w matches. I read somewhere you need to shuffle 7 times to achieve fairly complete randomness with a poker deck.
