Jack Frost can definitely learn Dia, probably Zio and Zan also, though I won't be able to get them all at once. Shikigami is pretty useful, he usually holds his own for quite awhile. I'm a fan, but Jack Frost is legit too. Awhile ago I started a tradition where I never fuse away my Jack Frost. Persona 3, Devil Survivor, Devil Summoner, Strange Journey, I keep my Jack Frost to endgame. He's just such a good guy, I can't bring myself to abandon him.
Yeah either one works. If I fuse Pixie away, so long as I still have something with the original Pixie in it, it'll transform. So tell me to do whatever you wish with her.
Starting up the game now, update coming eventually.
