Errata » Seed Flare
Shaymin LV.X is receiving errata for its "Seed Flare" attack. Seed Flare does additional damage for each Grass Energy card attached during the attack, rather than each Grass Energy attached during the attack. The correct card text should read, "Choose as many Grass Energy cards from your hand as you like and attach them to your Pokémon in any way you like. If you do, this attack does 40 damage plus 20 more damage for each Grass Energy card attached in this way."

Errata » Evolutionary Gas
Skuntank is receiving errata for its "Evolutionary Gas" Poké-Power. Evolutionary Gas's effect ends when the Defending Pokémon is no longer the opponent's Active Pokémon. The correct card text should read, "Once during your turn (before your attack), when you play Skuntank from your hand to evolve 1 of your Active Pokémon, you may choose 1 of the Defending Pokémon. If that Pokémon tries to attack during your opponent's next turn, that attack does nothing. (If the Defending Pokémon is no longer your opponent's Active Pokémon, this effect ends.)"

Errata » Dialga
Dialga from the Platinum expansion is receiving errata to address an incorrect card template for the parallel holo version of the card. Dialga (Platinum, 23/127) should use the Metal-type card template, rather than the Colorless-type card template.

Abilities » Vessel of Life
Can I use Shedinja's "Vessel of Life" Ability to attach it to a Pokemon that already has another Pokemon Tool card attached?
No, you cannot; the rulebook states "each Pokemon can have only 1 Pokemon Tool attached at any time". However, if there's an effect that overrides that rule, such as Genesect GX's "Double Drive" Ability, then you would be able to attach Shedinja to a Pokemon that already has another Pokemon Tool card attached.

Energy » Rainbow Energy
If I have an attack that says to discard a Fire Energy and a Water Energy, may I discard a single Rainbow Energy card or Multi Energy card to satisfy that requirement?
No, even though Rainbow and Multi provide all energy types simultaneously, they only provide one unit of energy. You can discard it for either the Fire or the Water, but you would still need to discard at least one additional card of the required type.

Attacks » Shadow Room
If Gengar uses "Shadow Room" against a Lv.X Pokemon that has no Poke-POWER, but the card underneath the Lv.X *does* have a Poke-POWER, does "Shadow Room" place three or six damage counters?
The Lv.X Pokemon has the Poke-POWERs and Poke-BODYs from the card underneath it, so Shadow Room would place six damage counters in this situation.

Abilities » *Abilities in General
If I intend to use a Poke-POWER [or Ability], do I have to announce its name or can I just take the action specified?
You have to clearly communicate your intent to use a Poke-POWER [or Ability] by some method other than just performing its game effect. Show or tell your opponent which Pokémon is going to use what Power.

Errata » Hidden Poison
Roserade is receiving errata for its Poke-BODY, "Hidden Poison". Hidden Poison affects your opponent's Attacking Pokemon, not your Defending Pokemon. The correct card text should read, "If Roserade is your Active Pokemon and is damaged by an opponent's attack (even if Roserade is Knocked Out), the Attacking Pokemon is now Poisoned."

Errata » Fainting Spell
Gengar is receiving errata for its Poke-POWER, "Fainting Spell". Fainting Spell affects your opponent's Attacking Pokemon, not your Defending Pokemon. The correct card text should read, "Once during your opponent's turn, if Gengar would be Knocked Out by damage from an attack, you may flip a coin. If heads, the Attacking Pokémon is Knocked Out."
