Generally I have always been offense with very few supporting moves. Although that is starting to change now. In Black, I did a run through with Ferroseed and using a leech seed set in combination with rocky helmet and the aid of Ferroseed's ability. Almost nothing could kill this thing. I once was battling a Trubbish that was stupid enough to us doubleslap and the dumb thing killed itself without me having to do a thing. But I still lean on the side of offense, but trying out new sets is pretty cool too.
