I dont think that Mega-Salamence is the worlds greatest mega but it is defineatly good! The problems with this mega are getting bodied by too many of the other megas. Mega-Altaria is definealty an issue because of typing and defense stat. Mega Sharpedo is a problem because if normal sharpedo gets enogh speed boosts off then mega evolves, it can OHKO with an ice fang. Other that that I dont see anything wrong with this mega!
