If I use Fantina and then my Flying Pikachu V with Big Parasol attached uses its "Fly" attack and successfully lands heads, would my opponent's Giratina V's "Shred" attack do any damage to Flying Pikachu V or not?
Shred isn't affected by "any effects on the Defending Pokemon"; so the effects from Fantina and Big Parasol and Fly would all be ignored, and Shred would do damage.

If my Snorlax is affected by its "Thumping Snore" attack but then on my opponent's turn they use an effect that puts Snorlax to sleep, does the 2 coin flip effect of "Thumping Snore" get replaced by the regular 1 coin flip effect during Pokemon Checkup?
The newer sleep condition would replace Thumping Snore’s sleep condition, so you would now only have to flip 1 coin instead of 2.

When Snorlax uses its "Thumping Snore" attack, how long does the effect of having to flip 2 coins during Pokemon Checkup while Asleep last?
The effect lasts either until Snorlax wakes up or it moves out of the Active Spot.

If I use Malamar's "Synchro Kinesis" attack and the only card that each of us have in common are Basic Energy cards, do I get to do the extra damage or not?
If you and your opponent both have Basic Energy of the same type in your hands, it's a match. Professor's Research and Boss's Orders with different characters on them also count as matches.

Do I have to have Tool cards in my discard pile in order to use Rotom V's "Scrap Short" attack? Or if I have Tool cards in my discard pile, do I have to choose at least one of them to put into the Lost Zone?
You can use Scrap Short if you don't have any Tool cards in your discard pile. Scrap Short does not require you to put any Tool cards into the Lost Zone; if you cannot or choose not to put any Tool cards into the Lost Zone it only does the base amount of damage.

If I have 5 cards in my Lost Zone and my opponent has 5 cards in their Lost Zone, can I use Sableye's "Lost Mine" or Giratina VSTAR's "Star Requiem" attack or Fantina?
No. Each player has a separate Lost Zone above their Prize Cards that they put cards into. You yourself must have 10 cards in your Lost Zone in order to do either of those attacks or to play Fantina.

If I have a Poliwrath on my bench that evolved from a Poliwag and a Poliwhirl do I get all of the damage bonuses for each of them?
No, you only look at the most evolved stage of a Pokemon in play. The previous stages are now part of that Pokemon.

If I have multiple Poliwag on my bench, does Politoed's "Lordly Songleader" attack do additional damage for each of those Pokemon?
You only get the additional bonus once per Pokemon named in the attack. For example, if you have two or more Poliwag on the bench you only get to add +60 once.
