Diancie is a Steel & Fairy type, and is the last mythical I am taking out of this ranking. Now, when it comes to design, I find it the best designed from the three mythicals, and it stands out the most to me at the least. When I think of the mythicals of Kalos, Diancie tends to be the one that pops in my head first, much more memorable than the other two. Anyways, Diancie has good stats, okay abilities (good abilily with its mega form though,) and a decent movepool. Then there is Mega Diancie, which is much better battling wise than regular Diancie, but both are pretty viable. Sure Diancie is cool, but just not quite cool enough to make it any further.
