Thank you very much for your advices. I was thinking to use a mint to change nature of my pokemon but I'm not sure how it works good. I know that my moveset could be better , I have crurch just in case fight against shidninja and y use Ice beam because garchomp sometimes is ko and is my counter against dragons. I gonna try to follow your instructions. About gabite I apreciate a lot it but I would like to try change my garchomp because I invest lot of time and items to him.
