The damage from Tyranitar's "Power Claw" attack isn't affected by Poke-POWERS, Poke-BODIES, or any other effects on the Defending Pokemon. Would you apply weakness and resistance to its damage?
Yes, weakness or resistance to Tyrantitar's type would be applied where appropriate. These are game rules and not considered effects on the Defending Pokemon.

My Larvitar is poisoned with 10 HP left. My opponent has one prize remaining and no cards in the deck. Can I attack with "Mountain Eater" and win the game?
You can attack, but if you can't discard the card you don't get to remove two damage counters. Larvitar will be KO'd between turns and your opponent will take the last prize.

When I use Shaymin's "Celebration Wind" Poke-POWER, can I move my energy cards in play around to any and all of my Pokemon that I want, or just to one Pokemon?
You can move the energy cards from more than one Pokemon and move them to more than one Pokemon, as desired. However, once you have taken another action, like playing a Pokemon card onto your bench, attaching an energy card from your hand, retreating your Active Pokemon, etc. you can no longer move any energy cards around.

Three cards have been added to the list of errata for the Pokémon Trading Card Game. [...] The text below reflects what the card should say, not what was originally printed. "When the Pokémon this card is attached to is Knocked Out by damage from an opponent's attack and put into your discard pile, draw cards until you have 7 cards in your hand." If the Pokémon does not go to the discard pile (for example, if it goes to the Lost Zone, etc.), you do not get to draw the cards.
