OK screw it tagging and double posting time, because people don't seem to read threads fully but do seem to pay attention when they're tagged.
The Reptile, you can run Lunatone as type/Psychic if you want. Maybe help distinguish it from Solrock.
Kit Kasai, you can run Solrock as type/Psychic too, though I think it's fine as is.
TheBurgerKing99, I imagine you're fine with Durant as is, but it can always be type/Steel instead if you like.
Mczatar, you can switch Chatot to always being a bird if you like, though to be fair STAB Boomburst is one of Chatot's main draws.
ladt2000, you can make Sigilyph a type/Flying if you care more about its birdiness than its weirdness.
Togie, you can make Emolga... er... well, always Flying.
birdcrest PLEASE I BEG OF YOU MAKE ARTICUNO ALWAYS A BIRD PLEASE Also I guess there's Relicanth, but I'm not clear how that whole thing with you and
Lennon1398 is supposed to work.
Throbulator36, you can make Cobalion always Steel typed!
CrazyGuy108, you can make bird santa always a bird rather than always a santa!
warriorman222, Meloetta and Spiritomb don't have to be locked to Normal/type and Ghost/type if you don't want them to.
MegaGallade, you can make Tropius always a flying whatsit rather than always a plant whatsit. Admittedly, that would be
really weird given Tropius' Abilities...
simsims2800, you can make Moltres always a bird! I dunno if you care, but I would like to note that Sky Attack, which is sort of a signature move of Moltres, is called "God Bird" in the Japanese.
Mantodea, Corsola is free to choose between its Water heritage or its Rocky heritage of ancient coralness!
Molk, Farfetch'd can always be a bird! But I'm pretty sure you're happy with it as-is.
zezleijon, Virizion can always be Grass-typ -OK who am I kidding.
Flying Types Rule!, Stunfisk... eeehh... well, if you wanna change its typing, you can do that.
NixHex, Dedenne can embrace its Fairy heritage! Which is admittedly an awful fit to its movepool, but
know that this suboptimal choice is available to you now!
Now I'll assume if people don't respond that they just don't feel like making such changes.
Also here's a question The Eevee General: Do all the variations need to have a type in common, or do they just need to all share a type with the original? You didn't object to my Regirock entry, where one of its variants was a replacement instead of an addition, but that doesn't necessarily clarify if, for instance, Lunatone could have some Formes Rock/type and others Psychic/type or not. This is relevant both because people may or may not be going back and changing things but also because it matters for the future creations.
