here is the way me and my friends play: ( sorta like the BVG )Arenasif we are playing on the square-shaped arena, each darkus bakugan gains 200g and each pyrus bakugan is -50g if we are playing on the bakubowl arena, each pyrus bakugan are +200g each time they hit the ramp, and -50 if darkus bakugan hit the ramp.the special bakuganpyrus dragonoid - if you have any type of pyrus dragonoid in the game, you may choose to re-roll it 3 times per turn.aquos preyas - if you have any type of aquos preyas in the game, you may choose to switch the attribute of it to whatever it has on the wheel (if any) and if it is an aquos preyas angelo/diablo, you may choose to either drop it on a GC, or reroll it.haos tigrerra - if you have any type of haos tigrerra in the game, it gains an extra 100g for each ability you play.subterra gorem - if you have any type of subterra gorem in the game, you may activate a trap even if the trap isn't your attribute.ventus skyress - if you have any type of ventus skyress in the game, you may choose to make any ability of your choice that you have go to your unused pile for the rest of the game ( e.g. i have used the gust to boost skyress, so it still goes to my unused pile and i can use it again once per battle )darkus hydranoid - if you have any type of darkus hydranoid in the game, you may get a doom card and is part of the battlefield ( e.g. i play a doom card at the start of the game, now if i defeat an opponent's bakugan, it is taken out of the game ) and hydranoid's printed g-power is +20g for the rest of the game.
