>>53909553Right now Ralts can't even be found in the wild (or very rarely, haven't seen them lately), only a chance to be found in research tasks, which you may or may not find.
You'd also need 25 candy to evolve into Kirlia and then 100 to Gardevoir. Each catch grants you 3 (increased to 6 if Pinap Berry is used).
If you want a shiny one, then I don't have any good news for you. And if you want a mega, then I have worse - not in plans for the current 3-months season which has just begun. And when it comes around (fuck knows when) you'd need a group of players to do the raid with you, as niantic nerfed remote raiding to oblivion and getting random people to help you is MUCH harder.
TL;DR don't do it, the game's only worth it for Community Days when you go ham catching shit with increased shiny odds which you then transfer into mainlines
