I certainly don't have a problem with house rules, but only if they make the game more fun. I think the balanced games where you win or lose by the skin of your teeth are the most fun so my house rules are only used to try to make the game more balanced. I think playing Visionary's deck face up does not balance the game. It gives way too much advantage to the heroes. If you can't remember what you put on top, oh well. You can blame it on the brain hemmorhage Visionary has.
And you can only use AZ's deck after it's been in the freezer. ;)
I always hate driving next to people with loud music and high bass. I've heard from a friend that his friend went through cars faster than most people go through shoes, he always had the music so high it was literally shaking his car apart.
