It'd be cute if Diancie and Magnia or w/e are in a trio and serve counter parts to the Regi trio. Rock/Steel/Ice. The Regi trio speculated to be involved with AZOTH and AZOTH the city appearing in the movie (I think) with that thing there. Serve me Ice/Fairy next
So I just saw Magiana... eh. Its design is alright, but a little cutesy for my taste. I think it's pretty obvious that at least one of its types is going to be Steel. I'd bet on Steel/Fairy.
