If I use Parasect's "Lethargy Spore" Ability after a Pokemon has been attacked by Dustox's "Nadir Powder", how many counters are placed on the poisoned Pokemon during Pokemon checkup?
Lethargy Spore resets any specific number of damage counters for Poison to 1, therefore overriding Nadir Powder's effect of 8 damage counters for Poison.

If I use Drapion VSTAR's "Hazard Star" VSTAR Ability to poison my opponent's Pokemon with 3 damage counters during Pokemon Checkup, and I have Radiant Hisuian Sneasler with the "Poison Peak" Ability in play, does my opponent put 3 or 5 damage counters on their poisoned Pokemon during checkup?
Five damage counters. Poison Peak adds 2 damage counters to whatever the current number of damage counters are being placed for poison.

Can I make an entire deck with jumbo sized cards to be used in a sanctioned tournament as long as they are all the same uniform size?
No, you cannot. You may only use cards that have been released for TCG play in the standard size. Jumbo cards are artistic representations of the legal card's art.

Do I use Radiant Venusaur's "Sunny Bloom" Ability before or after taking prize cards at the end of my turn?
Sunny Bloom is used at the end of your turn after attacking and checking for a KO but before Pokemon Checkup. So if your attack causes a KO, you would take Prize cards first, and then get to use Sunny Bloom.

If my opponent KO'd one of my Pokemon and then on my next turn I use Origin Forme Dialga VSTAR's "Star Chronos" attack, or if I KO one of my opponent's Pokemon with Medicham V's "Yoga Loop" attack, can I play Raihan on the second of my two turns from either of those attacks?
Yes, you can. Your Pokemon was KO'd "during your opponent's last turn" regardless of how many turns you take since then.

Can I play Gutsy Pickaxe if I have no Benched Pokemon?
No, you cannot. Since it is mandatory to attach a Fighting Energy if you draw one, you have to have a Benched Pokemon in order to play the card.
