I haven't seen anyone give a reason why drawing (like autographing) within the picture is bad in any way.
And if people start getting penalties because they've been shuffling their deck all day, there is seriously a problem with the game. Obviously 4 creases on 4 Rare Candy is a different situation but if judges are going to give out dqs or even prize penalties (which could be eliminations too) for RANDOM UNCONTROLLABLE WEARING because players are guilty of shuffling, then there's a serious problem here. I don't think this really happened hearing the anecdotes of nationals, but some of these overcautious message on this thread are scary. Players shouldn't have to worry about this. I don't want to change sleeves after 4 rounds, I think it's more likely I'd do that and my new slippery sleeves fall over during the game and get me a game loss. This is a legitimate concern with new sleeves. I'll have new sleeves before a worlds or a nationals but even I shuffle intensely for that long waiting time to get rid of this problem, something you couldn't do between rounds.
