The original text for Venusaur & Snivy-GX's "Shining Vine" Ability was: "Once during your turn, if this Pokemon is your Active Pokemon, when you attach a Grass Energy card from your hand to it, you may switch 1 of your opponent's Benched Pokemon with their Active Pokemon." The new card text for Venusaur & Snivy-GX's "Shining Vine" Ability will be: "During your turn, if this Pokemon is your Active Pokemon, whenever you attach a Grass Energy card from your hand to it, you may switch 1 of your opponent's Benched Pokemon with their Active Pokemon."

The original text for Minior's "Far-Flying Meteor" Ability was: "Once during your turn, if this Pokemon is on your Bench, when you attach an Energy card from your hand to this Pokemon, you may switch it with your Active Pokemon." The original intention was to be able to use this Ability whenever you attach an Energy card from your hand to this Pokemon, not just once per turn. It is possible to use this Ability more than once per turn. The new card text for Minior's "Far-Flying Meteor" Ability will be: "During your turn, if this Pokemon is on your Bench, whenever you attach an Energy card from your hand to this Pokemon, you may switch it with your Active Pokemon."

What happens if I use Area Zero Underdepths to replace Sky Field, or vice versa? Does either player need to discard Pokemon because the Sky Field/Area Zero Underdepths stadium left play, or is the transition instantaneous?
As long as you meet the required criteria of the new stadium you would not have to discard any Benched Pokemon since one stadium's effect is replacing the other simultaneously.

If I use Grand Tree to evolve from Charmander into Charmeleon and then into Charizard ex, can I use Charizard ex's "Infernal Reign" Ability or not?
No, you cannot use Infernal Reign because Charizard ex was not played from your hand to evolve Charmeleon.

Say my opponent and I each have 1 prize card left, then I use an attack like Pumpkaboo's "Reckless Charge" that KO's my opponent's Active Pokemon but also KO's Pumpkaboo due to "Reckless Charge's" recoil effect. However, my opponent has only one benched Pokemon with 20HP left, while I only have Iron Valiant ex on my bench. Does our game go to a tiebreaker since we both have a Pokemon on the bench, or will I win the game since Iron Valiant ex would be promoted as Active and then "Tachyon Bits" will be activated resulting in the KO of my opponent's last Pokemon?
All effects have to finish resolving before the winner is determined, so you could activate Tachyon Bits to KO the opponent's last Pokemon. You would win the game as you have achieved two win conditions but your opponent has only achieved one.

If Roaring Moon ex's "Calamity Storm" attacks a Pokemon without a Rule Box and chooses to discard the Neutralization Zone stadium, is the damage neutralized before discarding the stadium, or does the damage happen after discarding the stadium?
The *choice* is made to discard the Stadium and damage is calculated, however Neutralization Zone stadium prevents that damage from being done. After that the Stadium is discarded.

If Haxorus uses its "Bring Down the Axe" attack while Temple of Sinnoh is in play and there is a Mist Energy attached to the Defending Pokemon, does it knock out the Defending Pokemon?
Yes. Even though Temple of Sinnoh turns off the text portion of Mist Energy, it still remains a Special Energy Card and meets the requirement for Bring Down the Axe.

If my opponent has a card with "Colress" in its name in their Discard Pile and Pokemon League Headquarters is in play, can I use Kyurem's "Trifrost" attack with only one energy attached due to its "Plasma Bane" Ability?
Kyurem's Plasma Bane ability sets Trifrost's attack cost to one. Since the attack cost has been set to a specific number, Pokemon League Headquarters does not add to it.

My Wellspring Mask Ogerpon ex has a Sparkling Crystal attached and only one Double Turbo Energy on it. If I use its "Torrential Pump" attack, can I shuffle the Double Turbo Energy back into the deck and do damage to a benched Pokemon?
Yes, this is a case of doing as much as you can. You would get to do the bench damage even though you can't detach 3 energy, but you must shuffle in SOME energy in order to get the bonus. You shuffle the two energy that are attached back into the deck, and do 80 to the active and 100 to the bench (remember, damage is still reduced for the DTE since the detachment happens after damage is done).
