When using Celebi’s “Amazing Bloom” attack, can I search for a Stage 2 Pokemon and put it onto a Basic Pokemon if they’re in the same evolution line, for example from Charmander to Charizard?
No, Amazing Bloom does not let you skip stages.

If my opponent uses Exeggutor’s “Head Crack” attack, then my Active Pokemon retreats for another Pokemon that has the same attack name that was blocked, can my new Pokemon use that attack or is it blocked?
Head Crack places the effect on your Pokemon that was Active when attacked, so when that Pokemon is benched the effect of Head Crack ends.

If I play Nessa on my turn while my opponent has “Shifty Substitution” in effect, do I still get to Paralyze the opponent’s Active Pokemon if I use Drednaw’s “Vise Wave” attack?
Yes, because even though Shifty Substitution replaces Nessa’s usual effect the Supporter card still has the same name, so Vise Wave will still paralyze your opponent.

For Billowing Smoke, since prize cards are discarded when the Pokemon it's attached to gets KO'd, how does this interact with Dubwool V's "Revenge Blast" attack that "does 30 more damage for each Prize card your opponent has taken"?
Revenge Blast does not count any prizes that were discarded due to Billowing Smoke.

If my already-poisoned Pokemon is hit by Dragalge's "Poison Cultivation" attack then I use Switch while Dust Island is in play, is my new Active Pokemon poisoned with a regular condition (only one damage counter in between turns) or with the effect from "Poison Cultivation" (ten damage counters in between turns)?
If the Poison effect places more than one damage counter during the Pokémon Checkup phase between turns, then switching the Pokémon out using a Trainer card while Dust Island is in play will retain the modified Poison effect of placing multiple damage counters on the new Active Pokémon.

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.

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?
No, Hoopa was moved to the Active Spot during the opponent's turn, not during "this turn".

If I use Steenee's "Captivate" attack while Spikemuth stadium is in play, does the opponent put any damage counters on their Pokemon?
No, Captivate would not trigger Spikemuth since it was not moved during the opponent's turn.

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.

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.
