Double post, but it's an update based on the datamining so far.
New moves:
Psychic Terrain - Boosts Psychic moves, prevents grounded mon from getting hit by priority moves. Wow, Gamefreak must really regret making Talonflame. Not only we got TWO abilities for this, we also got a move to prevent priority.
Aurora Veil - Doubles Defense and Special Defense for 5 turns. This is going to be annoying. An INSTANT Reflect + Light Screen in one move? That's just... wow. I can see this can be annoying in something like Klefki or Cresselia.
Throat Chop - Prevents opponent from using sound based moves. RIP in pepperoni Boomburst Sylveon, Mega Gardevoir, Porygon-Z, Aurorus, Mega Glalie and any new -ate mons if there's anything new. Don't worry guys. We still have Techno Blast.
Laser Focus - Always Critical hit
Water Shuriken - Becomes Special. I can see Keldeo, Mega Blastoise, Volcanion as the new abuser of this. It seems cool, but well, we have tons of priority blocker now, so maybe it's less cooler than we thought.
