By the way- I feel like it might be good to not have Tristan's Exploud have boomburst, as at the point when you team up with him, outlevels you and whenever he uses it, he will probably kill the opposing Pokemon and kill you, removing any EXP you'd get. I've found that it causes a nasty problem with being underleveled at that point in the game, and on top of that there's no Audino trainer to help with that. After I finished Silver Rise I was 8 levels below basically all of Hardy's team which was very annoying.
