Since this topic is still alive, I’m up to 231 having finally evolved Apharos, so I think that is all evolvable ones caught. That’s at level 34.
Still missing the regionals in Gen 1 (seen all but Farfetch’d in gyms), and the legendaries (can’t find a group to take down an Articuno or Lugia, they’re around though). In Gen 2 just missing Unown, Heracross, Corsola, Delibird, Smeargle, plus the legendaries Raikou, Entei, Suicune, plus Lugia, Ho-Oh, and Celebi.
Be nice to get the two legendaries on offer in gyms, but pretty pointless trying it alone.
