Attacks » Devilish Hands GX
When using Hoopa GX's "Devilish Hands GX" attack, can I keep choosing a Pokemon that would already be Knocked Out by previous choices, or do I have to choose a different Pokemon once I have done enough damage to KO the first one?
You make all 6 choices before doing any damage; so if you wish, you can do more damage than you need to a Pokemon in order to knock it out.

Attacks » Drag Off
If my opponent has no benched Pokemon, do I do 50 damage to their active Pokemon when I use Nidoking's "Drag Off" attack?
No. Damage is only done to the "new Active Pokemon". If there is no switch, then no damage is done.

Attacks » Thunderous Assault
If my opponent Knocks Out my Active Pokemon and I promote my Zapdos to be Active after the attack, do I get the bonus 70 damage for "Thunderous Assault"?
No. In this scenario you promoted the Zapdos while it was still your opponent's turn. In order to get Thunderous Assault's additional damage it would have to become Active during YOUR turn.

Attacks » Copycat
When I use Mimikyu's "Copycat" attack, do I need to have the same required energy as the opponent's previous attack?
No, you only need whatever energy is required on Mimikyu in order to use its Copycat attack. However, if the attack requires you to do something with a particular type of energy you don't have, you cannot use that part of the copied attack.

Trainers » Ilima | Abilities » Victory Star | Attacks » Wink Wink
If I use Sylveon's "Wink Wink" attack to have my opponent discard Ilima, can I use Victini's "Victory Star" Ability to force my opponent to re-flip their coins?
Yes, you can. If your opponent flips a coin as part of your Pokemon's attack, you can use "Victory Star" to force them to re-flip those coins; but keep in mind you will have to re-flip your coins for Ilima too.

Trainers » Pokemon Ranger | Attacks » Shining Wind
If my opponent used Gardevoir EX's "Shining Wind" attack to gain "no Weakness" and I play Pokemon Ranger when it is my turn, does their Gardevoir EX have a Weakness again?
Yes. The ruling about effects on Weakness and Resistance not being ignored has to do with damage calculations [see "General Gameplay -> Weakness and Resistance" section for reference], not about whether a Pokemon HAS Weakness or Resistance. Pokemon Ranger removes attack effects, including this one; so yes, Gardevoir EX would have Weakness again after using Pokemon Ranger.

Attacks » Bell of Silence | Abilities » Mountain Pass
Does using Trumbeak's "Mountain Pass" Ability count as playing it from the hand? If so, would it be blocked if my opponent used Chimecho's "Bell of Silence" attack on the previous turn?
No, it is not being played from the hand. You are revealing the Trumbeak and then putting it into the Lost Zone; that is not blocked by Bell of Silence.
