If I use Gladion and choose to put Jirachi {*} into my hand, can I use Jirachi {*}'s "Wish Upon a Star" Ability?
Sorry, but Wish Upon a Star only triggers when you are taking it as a face-down prize card, not when you are trading it with another card.

Can Apricorn Maker be used to search for the Trainer "Bursting Balloon"? Taking the card literally, Bursting *BALL*oon contains the exact same "Ball" as given on Apricorn Maker.
Of course not, don't be silly! You can only search for cards like Poke Ball, Ultra Ball, Beast Ball, etc.

Can I use Wally or Evosoda on a Snorlax to search my deck, even though there is {currently} no evolution of Snorlax?
No, there has to at least be the possibility of a valid evolution in order to use this card. Sorry.

Can I use Wally or Evosoda to search my deck for a card that is not in the current tournament format? For example, could I use it on Raichu to search for a Raichu BREAK after it rotates out?
Yes, you can. Even though a card may not be in the tournament format it still exists and can be searched for even though it is known to fail.

I have 3 Pokemon on my Bench, and 1 of them has the "Omega Barrier" Ancient Trait. My opponent plays Cyrus {*}, and I choose to keep the 2 Pokemon that don't have "Omega Barrier". Does the Pokemon with "Omega Barrier" get shuffled into my deck?
Yes, it does. The effect of Cyrus {*} is on the player, not on the Pokemon with Omega Barrier.

If Lysandre Labs is in play and I use Primal Groudon's "Gaia Volcano" attack to discard the stadium and do enough damage for KO, what happens if the full HP Fighting-type Defending Pokemon has Focus Sash attached to it?
While Lysandre Labs is in play Focus Sash has no effect. However, Lysandre Labs is discarded as part of the attack before KO's are checked. So the Focus Sash would be in effect and if all of its conditions are met the Defending Pokemon is not KO'd but has 10HP remaining.

What happens if Shining Jirachi with Choice Band attached uses its "Stellar Reign" attack against an undamaged, evolved, Lucario GX with Focus Sash attached? Does Focus Sash save the Pokemon from a KO?
During the attack Stellar Reign would do 80 damage (10 for the attack plus 30 for the Choice Band, then times 2 for Weakness). Then the devolution part of Stellar Reign would return all Evolution cards to the opponent's hand. However, when KO's are checked the devolved Pokemon is not the same Pokemon that was attacked, so Focus Sash would not protect the newly devolved Pokemon. The original Pokemon took damage from the attack, and the lower Stage just happens to have enough damage on it for a KO.

Can I play Eneporter to try and fail to move a Special Energy onto a Pyroar that is protected by its "Unnerve" Ability, or would I not be able to play Eneporter at all?
The fact that its effect will be blocked by another effect such as Unnerve does not prevent an Item or Supporter card from being played. For example, your opponent may play Eneporter to try moving a Special Energy and Pyroar is a valid target, but Unnerve blocks the effect even though Eneporter was played. Playing a card for no effect happens when the game state itself prevents any effect from taking place and in that case the card would not be played, but that is not what this example is referring to.

If Lysandre Labs is in play, do effects that depend on the presence of Tool cards, such as the damage increase of Doublade's "Curse of the Blade" attack or the energy cost modification of Rotom's "Roto Motor" Ability still work?
If an effect depends simply on the presence of a Tool card in a certain location, the effect still works. It is the Tool card's effects that are cancelled, not effects based on the presence of a Tool.
