Alright, second part done!
First part: spritegirl.deviantart.com/art/…
Update August 30: Added Shiny version in the theory.
Ok, what happens here is simple: you can see how a Carbink "mutates" into a Diancie, step by step.
With all the details explained and with many numbers upon the Pokémon, you can see how much
differences there is between Carbink and Diancie.
I hope that these sketches of the special stages are good enough for everyone.
Next thing about Diancie will be about Diancie and Mega Diancie: the differences and full sketches between the two.
