>>57161224>>57161302Since you already have a fully-build and seeded Wiggly, just keep using it. As long as you are ending the day at full energy it doesn't really matter who you use.
Look at this comparison between your Wigglytuff and a "near-perfect" Gardevoir. It all amounts to a measly total of 7 extra berries per day from the berry mons. Not worth all the dream shards and seeds you would have to spend.
I would only consider a change if I were to get the God roll of a Ralts with Skill M + Help Speed M + Helping Bonus + Skill nature. And even that would be a questionable investment
unless it is also a shiny.
