Today, I am only 10 forms from completing my in-game living form dex excluding the use of HOME (which is not available yet) and another save file. The following Pokèmon/items/touch trades I need are:

• A touch trade to evolve Male Feebas into Milotic.
• A touch trade to evolve Porygon into Porygon 2.
• Another Prism Scale and a touch trade to evolve Female Feebas into Milotic.
• Another Upgrade, another Porygon, and a touch trade to evolve Porygon into Porygon2 and then Porygon-Z.
• Alolan Raichu in my own nickname.
• Hisuian Avalugg
• Malicious Armor to evolve Charcadet into Ceruledge.
• Virizion
• Cobalion
• Keldeo
  
  If I had another save file, I would be able to get Zygarde 10%, Keldeo Resolute, another Genesect form (would need 5 to get all), and Hoopa confined. HOME compatibility (or a future update) would allow the other 17 remaining Vivillon, Roaming Gimmighoul, Magearna in own name and Original color Magearna. If we count the mons (Scatterbug and Spewpa) that evolve into the different Vivillon forms, that’s another 38 I would need. Eternal Floette would presumably be locked to AZ for the foreseeable future.
