As it's attack is high, I'd mostly focus on physical moves.
X-sxissor is a good bug move (power 80, acuracy 100)
Dig is also an option to concider (power 80, acuracy 100) but it is a 2 turn move, so you'd have to watch out for oponents switching to flying pokemon or using Protect.
Although slash is normal type (power 70, acuracy 100) it could be a back up move for when you arn't very effective, like fighting a flying type.
More risky physical moves include Giga impact (power 150, ac. 90, can't move next turn. Don't go for hyper beam; it's the same exept special attack, where you arn't as strong.
If you wanted to incorperate some sp attack moves, although it's sp attack is low you could go for
Shadow Ball (power 80, acuracy 100)
Giga Drain (power 60, acuracy 100 +obtain 1/2 absorbed hp)
I wouldn't go for solar beam as it's 2 turn power is 120 and using giga drain in those 2 turns would do the same damage as well as gain you hp.
Overall, I might go for X-Scissor, Dig, Shadow Ball, and Slash
