Errata » Buffer
The Poké-BODY "Buffer" found on Hoppip, Skiploom, and Jumpluff should read, "If Hoppip/Skiploom/Jumpluff would be Knocked Out by damage from an opponent's attack, flip a coin...". So only attacks that do damage (not "place counters") would cause Buffer to be invoked.

Errata » Crush and Burn
Electrode-EX's "Crush and Burn" attack does extra damage based on the number of Energy cards discarded, not the amount of Energy provided. Official Wording: You may discard as many Energy cards as you like attached to your Pokémon in play. If you do, this attack does 30 damage plus 20 more damage for each Energy card you discarded.

Errata » Ripples
Mantine's Poké-POWER only works when it is the player's Active Pokémon. Official Wording: Once during your turn (before your attack), if Mantine is your Active Pokémon, you may remove 1 damage counter from 1 of your Pokémon (excluding Mantine). This power can't be used if Mantine is affected by a Special Condition.

Errata » Double Rainbow Energy
Double Rainbow Energy should be applied *before* applying Weakness and Resistance. This brings it in line with the Japanese version of the card.

Errata » Strength Charm
Strength Charm should read: "Whenever an attack from the Pokémon that Strength Charm is attached to does damage to the Active Pokémon (before applying Weakness and Resistance), the attack does 10 more damage. At the end of the turn in which the player attacks with the Pokémon that this card is attached to, discard Strength Charm." This errata replaces text of "after applying Weakness and Resistance" with "before applying Weakness and Resistance" [in the Team Aqua vs Team Magma print]. It is also clarified that it is removed after ANY attack that the Pokémon makes, not just attacks that do damage.

Errata » Steven's Advice
Steven's Advice should read: "Draw a number of cards up to the number of your opponent's Pokémon in play. If you have 7 or more cards (including this one) in your hand, you can't play this card." This errata replaces text of "more than 7" with "7 or more". If a player has 7 cards in his or her hand (including Steven's Advice), they cannot play the card.

Errata » Mt. Moon
Mt. Moon should read: "Any Pokémon (both yours and your opponent's) with maximum HP of 70 or less can't use any Poké-Powers." This errata replaces text of "less than 70" with "70 or less". If a Pokémon has a maximum HP of 70, that Pokémon cannot use a Poké-POWER while this Stadium card is in play.

Errata » Drowzee
For purposes of proper Pokémon names, treat all cards referring to "Drowsee" as "Drowzee". For example, you cannot have four "Drowsee" plus four "Drowzee" in your deck.

Errata » Brick Smash
EX Hidden Legends Machamp is receiving errata for its "Brick Smash" attack to bring it in line with the Japanese version of the card. Weakness should be applied to the damage that Machamp deals. It should read, "This attack's damage isn't affected by Resistance, Poké-Powers, Poké-Bodies, or any other effects on the Defending Pokémon."
