Hi there!
I'm now at the end of Ep.13 and I am grinding my double-Hail team, however I can't really test my team because of not having trainers or double wild Pokemon anywhere.
So I suggest on having things like battle tower would be cool. It don't have to get EVs and IVs and experience, just the place to test things out.
Ummm... I don't know if that's too much for some Anon like me but thanks for reading this anyway.
