Pokemon Diamond Story Mode Team?

Alright, get rid of Solarbeam, your Infernape should be fine with JUST sunny day to help out with fire moves, try fitting in a Nasty Plot in him too (raises Sp. Atk.), Your Heracross is fine, Torterra should definitely have Wood Hammer-he's a physical tank, he should be fine (if your concerned bout HP, have him hold Leftovers or a sitrus berry), Your Staraptor is fine, and Empoleon is alright-considering you can get rid of bubblebeam for something a little more useful, like ice beam/blizzard
