everstone suggestion
Forum-Index → Suggestions → Rejected → everstone suggestionIf you don't want your pokemon to evolve you just give it an everstone and it won't. If you want to evolve it later, then give it the everstone for now, then, when you want it to evolve, take away the everstone and level up your pokemon to evolve it.
Everstones are almost always in the shop, and they are pretty cheap too.
So no support from me.
(correct me if i'm wrong - i've only done this once long ago, so i am unaware if the method has changed somehow)
