I found out a trcik for that. Just roll your bakugan RELLY hard towards it and it should move it back just enough so it'll act as a stopper and your bakugan should either ope or stop on the card counting as a stand.
Yeah, Well that doesnt work with Atmos, Ive tried, it rotates him, and Its sucks, who else is a good blocker, oh, Verias, if you can get him sideways, its so hard to dodge him!
Freezer is a good blocker. The arms spread out evenly and make it almost impossible to position your bakugan. I played with my kid earlier and he was annoying and he was not even dead center on the card.
