^ Then it's fine with the exception of Rock Slide > Rock Blast.
Not much else to say , but Giga Drain is an alternative on Galvantula.
Imo a Scarf Moxie set on Heracross would work nicely as well.
In that case , Stone Edge might be better than Facade ; I've used a Scarf Moxie set before and you rarely use othe Moves anyways , you primarily use your Dual STAB's.
I'm feelin' electric tonight
Cruising down the coast goin' 'bout 99
Got my bad baby by my heavenly side
I know if I go, I'll die happy tonight
