Thank you for answering my query. Though, My doubt still persists.
Since, Body Slam is only a 3G Pre-evolution move, and I'm sorry to mention, but I was talking about Black. And Thunder Wave wouldn't cause any damage to my opponent, Togekiss has a very high Sp. Attack which can't be ignored, and Aura Sphere, though is a priority move, is a physical move, and it won't do much damage, because Togekiss has a very low Phy. Attack
With only one attacking move, I don't think this moveset would be much helpful in competitive battling. But, it's a very good for my game otherwise!
