Topic: is using a reset bag after fully training bad?

If you use fully super train a Pokemon and use a reset bag after to reset stats is that a bad thing? Or will it be like you never completed it at all? i wanted to change one of my Pokemon from attack to special attack and I dont want want it to affect my pokemons ability overall xP

It will just clear its effort values.

When you train it up once more it will be ready to fight again.

Thank you!!
