Does Carracosta's "Ancient Custom" Ability negate Stealthy Hood? Or does Stealthy Hood prevent "Ancient Custom" from affecting the Pokemon Stealthy Hood is attached to?
Stealthy Hood prevents Ancient Custom's effect on the Pokemon Stealthy Hood is attached to.

I understand if I use Phione's "Whirlpool Suction" Ability and target my opponent's Pokemon with Stealthy Hood attached the effects get blocked. But what happens if later in that turn I use Tool Scrapper to remove Stealthy Hood. Would I then be able to use Phione's "Whirlpool Suction" Ability or has it already been used up at that point?
Sorry, even though Stealthy Hood blocked the Whirlpool Suction Ability it's considered to be already used. You attempt to use the Ability and the effect doesn't work, but you have still used the Ability and cannot try again.

If my opponent has Jirachi GX with "Psychic Zone" Ability, does Golurk's "Theta Stop" Ancient Trait bypass "Psychic Zone" and apply Weakness?
Psychic Zone will not be applied to Golurk because of Theta Stop, so any attacks done to Golurk would still apply Weakness. Attacks done by Golurk wouldn't be affected

Does Aerodactyl GX's "Primal Winds" Ability add {*} to the cost of an attack used by Mewtwo & Mew GX's "Perfection" Ability if it tries to use an attack from a non-Basic Pokemon?
Yes, it does. Mewtwo & Mew GX is still a Basic Pokemon; it doesn't matter whether Perfection uses the attack from a non-Basic Pokemon or not.

When using Mawile GX's "Captivating Wink" Ability to put Pokemon onto my opponent's Bench, are they allowed to evolve those Pokemon on their next turn since they just came into play?
Yes, as long as it's not the opponent's first turn of the game they can evolve those Pokemon if they are able to do so. It is a basic game rule that neither player can normally evolve any Pokemon on their first turn of the game, even if they are going second.

If a Pokemon was attacked with Lunala GX's "Moongeist Beam", does that block Mallow & Lana from healing it?
The first part of Mallow & Lana says to switch your Active Pokemon with one of your Benched Pokemon. When your Pokemon is switched the effect of Moongeist Beam is removed, so then you can heal the Pokemon once it is on the Bench.

Can you use Naganadel & Guzzlord GX's "Violent Appetite" Ability to discard a Pokemon if Naganadel & Guzzlord GX is not damaged?

Is there an order to Oranguru's "Primate Wisdom" Ability? For example, can a player look at the top card before picking a card from their hand to put on the top of your deck? Or do they have to pick the card from their hand first?
The text of Primate Wisdom says to switch the card. This happens at the same time, so no you do not get to look at the top card of your deck first.

If I use Phione's "Whirlpool Suction" Ability and target my opponent's Pokemon with Stealthy Hood attached I know the Pokemon with Stealthy Hood does not move. But would I be able to discard all cards attached to Phione and put it on the bottom of my deck?
No. Since Stealthy Hood blocks the move effect of Whirlpool Suction, the "if you do" clause fails and Phione stays in play.

Say Sky Field is in play and I have 8 Benched Pokemon, then I use Marshadow's "Resetting Hole" Ability. Do I discard Marshadow first and then discard down to 5 Benched Pokemon for the removal of Sky Field, or do I discard down to 5 Benched Pokemon first and then discard Marshadow?
The player who owns Marshadow can choose the order of discarding Benched Pokemon, either before or after the removal of Sky Field.
