If you wanna fuck heavily with Delta Species maybe have a distinction between "Natural" and "Unnatural" instances like the TCG did, just maybe done a little better (pretty much every unnatural Delta Species pokemon was an electric or steel type while the natural ones from the islands had all the interesting setups). Obv you don't have to follow any rules but maybe try for irradiated, Holon Delta Species pokemon to be the ones who have their ordinary types, and the Delta Islands pokemon be the fully type-mutated sort. The islands were stated to be "far away" from Holon but honestly fuck that and just have the crystal islands be a surrounding island chain if you use them.
If you want any like, crystalline tiles to work with in game boy style I can hook you up as long as you don't mind me keeping them for my project as well.
