Lol I wouldn't say expert but thanks. Here's the thread you should check out. The line looks pretty long but since the post about the tutor program hasn't been updated in a while, the line might be thinning out with tutors accepting new waves of students. The most important thing you can do right now is to respond to that thread saying that you would like to be tutored; then it's just a matter of waiting.
A main key to taking down a BP team is to recognize it is one immediately and counter before they can set up something great with it.
You can roar/whirlwind before your opponent sets up ingrain...this causes them to lose all their boosts and yah, lol, cripple them. Once ingrain is set up and they have enough boosts, it becomes very difficult to counter imo save an explosion or something to stop the chain...and then...even explosion might not kill at all if they have enough acid armors up.
