The title basically says it all, i was doing a Dragon Monorun, but i would like to make a team from the rarest and hardest to get Pokemon, just in case.
So, obviously, Poipole/Naganadel is the hardest one, cause completing the dex is a massive time sink, requires a huge patience, googling and community help. So that is one.
I feel like Mimikyu is also pretty obscure, running around like a moron in the desert for 4 hours is torture enough, and after finding the Mirage Tower it's easy to complete everything, get your Aegislash and forget about it, so i feel like comparatively not many people will even find the basement. So this is the second one.
Maybe you can make a case for a Spiritomb, since Odd Keystone got absolutely nonexistent chance of appearing during the mining, although it will be buffed to 1% in the final version.
What other pokemon are currently the hardest to obtain, rarest and most obscure currently?
