Thanks. I thought the Tangrowth was going to be a little awkward, but he actually does well. I didn't know that it had such good defense. It really, really helps.
That one looks good, but after playing through Johto...I really suggest keeping them all at the same level rather than having the levels scattered around. I normally don't like the conformity of them all on the same level, but it's a better idea. The GSC level problem still stands, unfortunately.
