I think that ZoroRoc is going to be really good post rotation, because it has good Mach ups against Malamar, and Buzzwole GX, and with all the decks with Zoro in them for consistency, Lycanroc is also pretty good as well. Even though we loose Mew EX and Mewtwo, witch are 2 of the best Buzzwole counters in the game, we get a new Deoxys that has the same attack as Mewtwo anyways.
