I think this strikes a nice balance overall, personally I like the beta Fire Starter more than the Cyndaquil line, it just looks nicer imo. As for removed Johto Pokemon;
- Sudowoodo was removed simply because I don't like it that much, you could feasibly have it become a Gen 4 Pokemon alongside Bonsly though to compensate.
- Unown, Delibird, Stantler, Smeargle & Wobbuffet were removed because I simply don't like them at all.
- Girafarig would've been included with its pre-evo if the two flowed better
- Pineco and Forretress just draw the short straw when it came to that group of Grass & Bug Pokemon in the fifth last row.
- Dunsparce just doesn't seem to ever be considered that much so it lost out to the other mountainous Pokemon
- Steelix was a tough one because it was going to be it or Porygon2 but I opted for the latter since Steelix could easily reappear in Gen 4
- Snubbull and Granbull were removed because I don't like their line that much mainly because of Snubbull, Granbull's actually pretty alright, but they could reappear in Gen 6 to bolster that one's dex a bit.
- Shuckle & Corsola was other casualties of the limited space this time in the set of marine Pokemon in the fourth last row
- Smoochum was removed because I feel given the beta dex they wanted Jynx & Mr. Mime to be parallels so I think Smoochum could appear as a Gen 4 baby Pokemon.
