Why would you use these?

To raise your pokémon's value by one

I'm going out on a limb and guessing that you're retarded.

To level up a pokemon without battling for EXP or using the daycare

Because I have them

>>27534893
Because I already ev trained my pokemon so grinding seems tedious by comparison.

If Im trying to evolve my pokemon into a Goodra and its raining on a shit route with weakmons that cant get me exp in a reasonable amount of time.

>>27534893
I use them for the revive effect, add a super potion and your fine for another round, i dont buy shit before the league and those things are everywhere

To make my Pokemon level up by 1, dumbass.
