Okay, first thing, just because you CAN use abreviations, doesn't mean you should do it for everything. It makes it hard to read. "Garch" and "Emp" are just lazy >_>
Anyway, Legends Awakened will definitely see play. Magmortar/Typhlosion will be making a comeback, with Claydol. However, like Dragonfruit pointed out, Kingdra and Politoed run through that. G&G-Plox will still be around, but with each new set, it will die a little more.
Garchomp will rise, as will the Eeveelutions.
But, Kingdra will dominate, along with Magnezone, Mewtwo, and the pixies/fairies/dwarfs/whateveryouwanttocallthem
