Did a game recently and we came across something that we weren't entirely sure on. The situation goes with a guzzlord gx out with buff pads on. A dark city stadium is played. Would that null out the buff pad effect?
Why do you think it would not nullify it?
With any card interaction, there should be an allowance (even a minuscule one) that the intent of the Japanese cards was lost in the wording, either the original Japanese or the local-language translation. Same for rulings themselves.
I find ruling questions are more effectively answered when the OP not only asks for the ruling but also explains why they think more than one answer is possible.
Pokémon Power: Rain Dance
As often as you like during your turn (before your attack), you may attach 1 [W] Energy card to 1 of your [W] Pokémon. (This doesn’t use up your 1 Energy card attachment for the turn.) This power can’t be used if Blastoise is Asleep, Confused, or Paralyzed.
Attach Rainbow Energy to 1 of your Pokémon. While in play, Rainbow Energy counts as every type of basic Energy but only provides 1 Energy at a time. (Doesn’t count as a basic Energy card when not in play.) When you attach this card from your hand to 1 of your Pokémon, it does 10 damage to that Pokémon. (Don’t apply Weakness and Resistance.)
Pokémon Power: Energy Evolution
Whenever you attach an Energy card to Eevee, flip a coin. If heads, search your deck for a card that evolves from Eevee that is the same type as the Energy card you attached to Eevee. Attach that card to Eevee. This counts as evolving Eevee. Shuffle your deck afterward. This power can’t be used if Eevee is Asleep, Confused, or Paralyzed.
Poké-BODY: Pure Body
To attach a [W] Energy card from your hand to Suicune, you must discard an Energy card attached to Suicune. (Attach the [W] Energy, and then discard an Energy card from Suicune.)
