>>42742650You can't actually use any pokemon transferred in from Pokemon Go in the few games that allow transfers. They are just there to look pretty. Also pokemon Tranferred into Pokemon Go can't be used in Pokemon Go so that won't work, either. It's a dead-end thus far and has been for years now.
> Relying on events only to get regional forms and complete your dexThis is not viable. Event mons often are special in some way such as having unique moves, too, which doesn't help.
> Safari ZoneIs there anywhere in Galar where you can roam about and catch random alolan forms? If so, how many out of all the aloans can you catch? This should answer your question as to if this is viable (hint: nope).
>>42742653If Pokemon Tundra included all of Galar plus two new islands and all the new regional, sure! It would be like Crystal: fun, expansive and beloved.
But, unlike real third games, you need TWO expansion passes to get all of the new mons: one for each game. That's $80 in DLC alone spread across two save games on two carts. A third version and a new save would be cheaper better overall, IMHO.
