Hi, I'm still lvl.72, I currently have 6 metal keys and could get more using Merit pts. I have several units I wanna max out and evolve, (Zenia, Sixgear, Jack, Miku, Ciara, Vernil, Rin etc.)

So, what's the best Metal Parade to farm in my current level? I already did several Metal Parades but I keep getting Ghosts.. Is Super and Mega Metal Parade worth the keys..?
