This is semi-interesting, but this generation has brought about the first time, that this circle can be made ------>
It's pretty obvious how it works, each dual type shares one type with next Pokémon clockwise, with Arceus in the centre cos he can be any type lol.
Wow, I know it's not such a big deal, but I figured it was a point of slight interest.
I hope you like it....P.S. I have a lot of time on my hands!!
