Well to get the mystic potion your already going to be using mojave, so use like a pastave bee and you could get some crazy stuff. If I were you I'd go over to world of ball pythons and use their genetic calculator to try different pairings and see what comes out of it.

Is your Mystic Cinnamon a male or female? Age? Breeding size already or do you have time to buy a baby to raise and pair with it?

The main thing you want to keep in mind is pair to make combos that YOU want, if you like them and are excited by them, other people will be too.
