Azumarill can't learn Aqua Jet and Belly Drum. It's an illegal breeding combination.
This is a completely inferior SlowKing combo. As niko was saying, a lot of this is just odd. Venomoth is a terrible user of Huge Power, both will likely be KO'd before the combination gets moving, and even if it does take off it doesn't really do anything.
If you want to use Venomoth as a Skill Swap user, combo it with Salamence/Latias. Tinted Lens Dragon attacks are unresisted.
