If I have a Honchkrow V with "Boss Pockets" Ability and 190 damage on it and three Emergency Jelly tool cards are attached, do all of the tool cards trigger at the same time or do they trigger sequentially?
They trigger in sequence, so the first Emergency Jelly would remove 120 damage and get discarded, but the second & third Emergency Jelly would not trigger since there is now more than 30 HP remaining and no more damage would be healed.

Here's some info regarding Pokemon ex: • Older cards that refer to Pokemon-ex should include modern Pokemon ex. Pokemon-ex and Pokemon ex are the same. For example, "Gardevoir ex" from EX Sandstorm has the same name as "Gardevoir ex" from Scarlet & Violet. • Pokemon ex from the SV series have a Rule Box, but Pokemon ex from the original EX series do not have a Rule Box. • Pokemon ex are not Pokemon-EX. For example, "Gardevoir ex" from Scarlet & Violet does not have the same name as "Gardevoir-EX" from XY-Primal Clash. Case-sensitivity matters.

If I have 6 cards in my hand and use Mimikyu's "Impersonation" attack to discard Erika's Hospitality from my hand, can I use the effect of Erika's Hospitality?
Since you have 5 cards in your hand after discarding the Erika's Hospitality you can use its effect.

If Temple of Sinnoh is in play, can I use Archeops' "Primal Turbo" Ability to attach a Rapid Strike Energy from my deck to a non-Rapid Strike Pokemon?
Yes, you can use Primal Turbo to attach Rapid Strike Energy to a non-Rapid Strike Pokemon. Normally Rapid Strike Energy would be discarded immediately, but Temple of Sinnoh removes all effects of Special Energy attached to Pokemon, so Rapid Strike Energy would not be discarded. But if Temple of Sinnoh's effect goes away, then Rapid Strike Energy would be discarded.

What happens if Klefki with "Mischievous Lock" and Empoleon V with "Emperor's Eyes" Ability somehow both become active at the same time, like at the start of the game?
If Abilities activate at the same time, the Abilities of the player whose turn it is activate first.

If Empoleon V with "Emperor's Eyes" Ability is in the Active Spot and my opponent brings up a Klefki with "Mischievous Lock" into their Active Spot, whose abilities are turned off?
Since Emperor's Eyes was in effect before Klefki became active, it takes precedence and Mischievous Lock does not activate as long as Emperor's Eyes is in effect. The converse is also true, if Klefki were active first and Empoleon V is brought up, Emperor's Eyes would not activate.

Can I use Porygon-Z's "Crazy Code" Ability or Archeops' "Primal Turbo" Ability to attach Spiral Energy to a Pokemon that isn't a Rapid Strike Pokemon?
Yes you can, but then it would get discarded immediately. However, if that Pokemon was Paralyzed, Spiral Energy would remove the Special Condition.

Beginning with the Scarlet & Violet expansion, cards like Pokemon Catcher will now say "switch in 1 of your opponent's Benched Pokemon" to make it clear that the effect is on the Benched Pokemon. Likewise, the phrase "switch out" will be used if the effect is on the Active Pokemon. Older prints of these cards with different text that have the same game effect will therefore remain legal.

If my opponent's Florges used its "Moonblast" attack last turn, would my Kilowattrel's "Skill Dive" attack only do 20 damage to a Benched Pokemon?
Yes, all attack damage is reduced by 30. This damage reduction applies to all Defending Pokemon (including Benched Pokemon), and also applies to any self-damage done to your own Pokemon.
