Say Zoroark GX has Unit Energy {F}{D}{Y} and Rainbow energy attached and uses its "Trickster GX" attack to copy Arceus & Dialga & Palkia GX's "Altered Creation GX" attack. Can Zoroark GX use the extra effect of +1 prize for every KO from Altered Creation GX?
Nope, the two energy attached to Zoroark GX are used to pay for the Trickster GX attack (regardless of how much energy is required for the attack being copied), so in this case there is no "extra Water Energy" to permit the extra +1 prize effect.

When using Carnivine's "Return" attack, do I have to draw until there are five cards in my hand, or may I stop with less than five?
You do not have to draw any cards, but if you choose to do so you must end up with exactly five cards in your hand; no more, no less.

When using Centiscorch VMAX's "G-Max Centiferno" attack, do I get +40 more damage for the Fire energy I attach during the attack?
No, the attachment of Fire Energy from the discard pile takes place after the damage calculation of the attack is done. Also, you don't get to attach the Fire Energy if the attack didn't do any damage.

When using Centiscorch VMAX's "G-Max Centiferno" attack, can I get a Heat Energy from my discard pile?
No, you may not. Heat Energy only counts as a Fire Energy card while it is attached to a Pokemon, not when it is in the discard pile or anywhere else.

If my opponent has no benched Pokemon, does their Active Pokemon become Confused when I use Delcatty's "Captivating Tail" attack?
No. Confusion is only done to the "new Active Pokemon". If there is no switch, the Active Pokemon is not Confused.

If I use Steenee's "Captivate" attack while Spikemuth stadium is in play, does the opponent put any damage counters on their Pokemon?

If I use Hoopa's "Assault Gate" attack after I move it up to replace a Pokemon that was KO'd by an opponent's attack, does it do anything?

Can you use Pokemon Breeder's Nurturing to evolve Pokemon if Dracovich's "Primal Law" Ability is active?
Yes, you can still use Pokemon Breeder's Nurturing since the Pokemon is coming from the deck and not from your hand.

If you have 8 Darkness Pokemon on your bench including a Weavile, and you devolve it into a Water type Sneasel, can you discard just the Sneasel and stop, or do you have to continue discarding benched Pokemon down to 5?
Once you begin discarding Pokemon you must complete the full action of getting down to 5 benched Pokemon, even if you don't have any non-Darkness Pokemon on your bench any more.

If you have 2 Darkness Pokemon on the bench and an Eternatus VMAX with the "Eternal Zone" Ability, can you play a non-Darkness Pokemon onto your bench?
No, you cannot put any non-Darkness type Pokemon into play. This includes things that would put Darkness type Pokemon directly into play, not just playing them from your hand!
