Cross Chop is just as strong on Metagross, Bronzong, and Skarmory as Fire Punch. Close Combat is even stronger. The only stuff you'll use Fire Punch on are just as weak to or weaker to Ice Punch (Celebi, Exeggutor, Jumpluff...).
Burn Orb + Belly Drum is a horrible idea. You lose half your health to Belly Drum, then you lose 1/8 each turn? That gives you 4 turns to sweep, assuming you are never hit. If Sandstorm / Hail is in play, that chops it down to 2-3 turns (depending on whether you come in after something faints or not).
