Are there any good monsters that you could catch in the wild?
There are a few monsters that can be helpful for the average team. Just depends how good a team your trying to build? The fast knock backers are useful along with puff and rhino. There are some stunbombers that can be useful.
you also might want to pick up the purify/healers, Griffclaw, Skyblossum, archswan and shadeswan. Those guys can be quite handy for certain events.
