>>361955999/63 are only in Kanto
6/63 are only through trading.
6/63 are only 1% chance unless you get a phonecall
3/63 are only available through headbutting, which was a pain in the ass
2/63 needed stones, which were a pain to get
4/63 evolved through happiness, which was a chore if they weren't caught in Friend Balls (and two of those are eevee, who CAN'T be caught in a friend ball)
3/63 are roamers who appear whenever they fucking feel like it
1/63 WAS in Johto, but was only catchable after going to Kanto
1/63 was an event (we didn't get)
So that's more than half the dex which is either hard, awkward, or just generally annoying to get, and most of them are shit, or not worth using.
