I would recommend finding Speed Boosting nature of some type. Mewtwo's high speed tier is one of his greatest assets, to the point that even Stalltwo sets often run Timid.So I'm going to SR for Mewtwo and I dont have a Jolly or Naive Synchronizer. I do have an Adamant one. Would I lose anything major by going with Adamant? I probably won't use it online but I guess I'm asking for potential trade value if I hit on a perfect spread (and optimism for ORAS tutors)
