I'm pretty sure you just put the materials on a normal Power-Up Fusion. It's what the game's tip states at least.
So I got a Black and a Green Moltdra, a Fire Pengdra and a Ruby Carbuncle from the Pal Machine.
I'm aware that Pengdras are EXP Fusion Fodder, should I use him as-is or try to evolve him first? Ruby Dragons seem like a pain to get.
And what am I supposed to do with the Moltdras?
