Yesterday I got 10 closer by hatching Shellder, Scyther and Elekid and evolving into Cloyster and Electabuzz. Female Bellossom, two Slowking and two Scizor still need to be obtained by evolving via items found in the Sevii Islands. So just the 6 left for Kanto now (the Squirtle line) and 19 more Johto Pokémon.
