Power up or evolve first.

[JudgeDisco]

Evolve First cause if you power it up before evolving you will have less power as if you were to power it up than evolve it and besides we all want that strong pokemon that will destroy anyone who comes in our way so wynaut enjoy the game and destroy any and all trainers who come in our way also with gyms never join gyms that are weak unless you are willing to power them up cause you will get your butt kicked unless its a strong gym your in
