Anything with an insane amount of HP (over 300) is fake, as is any EX/GX or Pokémon Prime that isn't holo/shiny (except Championship prints, like your Mewtwo EX). Reshiram and Nidoking (wrong HP font), Charizard (unofficial foil pattern), Charmander (very thick borders), and Mewtwo (wrong fonts and bloated Energy icons) are also fake. Would need clearer images of the others to say for sure, but I speculate that Volcarona (very crooked) and Milotic (which seems to have thicker borders) are as well. If Team Plasma's Lugia EX isn't holo/shiny and textured or if Pikachu is missing the Lightning-shaped foil stamp-out on its texture, they're fake.
