Hmm...

It's hard to say. It's a very powerful team, I'll say that right now. The only thing I'm
looking at is Torterra's Razor Leaf. By fighting at such a high level, I would expect
Razor Leaf to be replaced with something stronger. Try replacing it, maybe for Rock tomb
so that flying types aren't too difficult, Giga Impact despite the fact that it needs
recharging, or Rock Smash for a Fighting move. Though it is good to have another Gr@ss
attack other than Leaf Storm, you could also try teaching it Gr@ss Knot, Energy Ball, or
Giga Drain.

Other than that your team is very good, better than many other teams out there, that's for
sure.
