If my opponent takes a prize and then I use Naganadel GX's "Injection GX" attack to add a prize to my opponent's Prize Cards, would my Dubwool V's "Revenge Blast" attack do only 120 damage because the number of prizes in my opponent's Prize Card area has increased? Or does it do 150 damage (120+30) because the opponent has already taken that prize (even though it is now back in the prize pile)?
Revenge Blast is based on the number of prize cards TAKEN, so even though the Prize Card gets put back into the opponent's area it still counts as +30 damage for Revenge Blast.

If my opponent used Lickilicky's "Selickt" attack, can I choose the option to discard from my hand if I have less than 3 cards in my hand?
If you have no cards in your hand, you must discard cards from your deck. But if you have at least 1 card in your hand, you can choose either option.

If I have Kingdra with the "Deep Sea King" Ability on the bench and my opponent uses Heatmor's "Burning Licks" attack that discards energy cards from my Active Pokemon and also knocks it out, can I move those energy cards to Kingdra before they are discarded?
No, the discard effect of the attack happens first, but you don't move energy for Deep Sea King until after you resolve the Knock Out.

When using Alolan Raichu's "Electro Rain" attack or Hoopa GX's "Devilish Hands GX" attack with a Telescopic Sight tool attached, would Telescopic Sight boost the damage to Pokemon-GX and Pokemon-V each and every time I choose that Pokemon?
Per the rule book you make all your choices first, calculate the damage, then apply modifiers (such as Telescopic Sight), and then apply damage to the chosen Pokemon. So you would not get to add +30 more than once if you choose the same Pokemon again and again; however if you choose multiple Pokemon-GX or Pokemon-V, you would get to add +30 to each of those.

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?

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.
