I'm having to replace the stadium my brother and I use because my dad accidenty stepped on it, but I have no idea what to get for just normal battles. Anyone have any suggestions?

Obviously the Attack type Beystadium is the best to recommend, as well as those that are legal for organised play in the World Beyblade Organization, but since it would be "for just normal battles", get what you want.

Also, you do not need to make a new topic for small questions like this. For this one, for instance, you should have used the Purchase Consultation thread.
