Can someone tell me all of the effects, cause I do not have the game 
im not sure on all the names so ill just put the attributessubterra -opponents gs go down 100 when u land on a card (I'm pretty sure this is what it does for DS, don't have a LV 3 Subterra yet.ventus-if you hit an opponent's bakugan, they are removed from the field, and you can't be CKO'dhaos-if you hit an opponent's bakugan, all of their bakugan are removed from the fielddarkus-can roll through terrain objects (like the sand mounds in the subterra field), and can't be CKO'dpyrus-get a highly increased Critical K.O. chanceaquos -infinite time to roll ur bakugan around to pick up g bonuses
fix'd for DSMy favorite is Haos, for Battle Royale, but Darkus and Ventus are pretty good too. I can get CKOs wthout the Pyrus shot (plus I don't use Pyrus), and Subterra and Aquos are pretty cool, but I don't use them either.
