Yeah, I agree. It might actually be an oversight since most pokémon can learn the same moves by TM as their pre-evolution.But what about Togekiss? It sort of has horns with its head spikes. It should be able to learn Smart Strike by TM just like Togetic.
I know that in BW, Cinccino wasn't able to learn Thief while Minccino could. This was fixed in the next set of games.
