I dont get how Shaymin could be a Truth counter. If you KO their active, they will just send up a benched and KO Shaymin for the game. IMO, I dont even see the Truth being played post Next Destinies because there will be so much Magnezone and Mewtwo.
EDIT: I also do not ever see Ultra Ball being more than a one of. You need to discard 2 cards, which can not be very helpful when you already have Junk Arm, and Junk Arm can get better stuff than Ultra Ball can. IMO, the best decks post Next Destinies will be either decks that can utilize Level Ball and Heavy Ball the most or just extremely powerful decks such as Mewtwo.
