I'd give it a 2, it's got a good item. But I feel that you're trying to use your STAB advantage too much.
Heat Wave's decent, But I'd get Flamethrower, More PP and Accuracy.
Fly's not too good in battles, unless your oppo has got a lot of Grass types.
Wing attack is a good to STAB with.
I wouldn' use Blast Burn, I'd rather Use Overheat, sure it does reduce SA, but it's damn useful to get you out of a sticky end.
I'd get SLASH or Dragon Claw, there's a chance of finching And a critical here
Flamethrower is slightly less powerful then Heat Wave, but with more PP and Accuracy, it's worth it
Double edge can be good to go, since you got some leftovers there
Earthquake can be a good attacj if used well
I'd say
Earthquake
Flamethrower
Double Edge/Dragon Claw/Slash
Wing Attack//Dragon Claw/Slash
