If I have Galarian Weezing with "Neutralizing Gas" active and my opponent brings up a Wobbuffet with "Bide Barrier" Ability, does "Bide Barrier" turn off "Neutralizing Gas" or vice versa?
Since Neutralizing Gas was in effect before Wobbuffet became active, it takes precedence and Bide Barricade does not activate as long as Neutralizing Gas is in effect. Whichever one comes into effect first would take priority in this situation.

If my Jumpluff with the "Fluffy Barrage" Ability attacks and KO's my opponent's Active Galarian Weezing with "Neutralizing Gas" Ability, can I attack a second time?
Yes, you can because Fluffy Barrage is no longer disabled.

If my Jumpluff with the "Fluffy Barrage" Ability attacks and KO's my opponent's Active Pokemon, do I get to attack again if my opponent promotes a Galarian Weezing with "Neutralizing Gas" Ability before the second attack?
No, because Neutralizing Gas disables Fluffy Barrage before Jumpluff can attack a second time.

What happens if my opponent has Malamar with the "Contrary" Ability active and I play Will?
Will lets you choose the first flip for an attack as Heads, but then Malamar's Contrary will treat it as Tails.

Can I use Liepard's "Trade" Ability if there are no cards in my deck, just to discard a card?
No, you can't use Trade if there aren't any cards left in your deck. Discarding a card from your hand is a cost to use the Ability, and drawing cards is the effect.

If I use Dusknoir's "Special Transfer" Ability to move an Aurora Energy to another Pokemon, do I have to discard a card from my hand per Aurora Energy's text?
Special Transfer is "moving" the Special Energy to another Pokemon, not "attaching" it like you would from your hand. So since the Aurora Energy is already in play you do not have to discard a card from your hand in this situation.

Can I use Dusknoir's "Special Transfer" Ability after I attack but before my turn ends to move Special Energy cards (such as Double Turbo Energy) off of my Active Pokemon?
No, once your attack ends, your turn ends.

If I play Garchomp with the "Sonic Slip" Ability to evolve my Active Pokemon and then Garchomp moves to the Bench, does the effect from "Sonic Slip" get removed?
No. It is an effect from an Ability, not from an Attack, so moving to the Bench does not remove it.

Does Cherubi's "Lively Fruit" Ability prevent an attack from moving or placing damage counters?
In the steps of resolving an attack, moving or "placing Damage Counters" counts as an Effect of the attack; it is not part of "doing damage". Therefore, as an Effect it would be prevented by Lively Fruit.

If I use Entei V's "Fleet Footed" Ability and retreat it for another one on my bench, can I use the new Entei V's "Fleet Footed" Ability too?
