Yep, Hi4H said that update with the first fight against Lysandre was his favorite he's posted so far, because the Fraxure survived the Gyarados' Outrage with 12 HP, and that was as a Fraxure. Now he has a Haxorus which should be able to ram through most of the rest of the game.
As for DINO, I'm thinking her replacement for that Whimsicott will be either Scraggy or Joltik - the former because it's super strong and has a solid nature, and the latter because it helps against Skyla, although she might give Thunder Fang to Cooper for that. But true, she spoke in Challenger's Clan about a death to Future Sight and that brought back bad memories alright.
