Sometimes, we feel like making our own rules. So I got together with some of my other Bakugan loving friends and made up our own rules.Rule 1: It's first to lose all their Bakugan to lose, which makes clean slate very helpful (especially because I use mainly Darkus).Rule 2: If you use all your ability cards, you get them back, unless you cannot use them again (like Rainbow Portal). This rule is very similar to the official rule about how when it's your turn, and you have no Bakugan to play, you get all Bakugan in your used pile back, only it's for your ability cards.Rule 3: You play the Doom Card at the beginning of the game, and only effects your opponent (meaning only your opponent's Bakugan is removed from play if they lose, not whoever loses). That way it is used almost exactly like it is in the anime.
