Say a player announced "double Afterburner" for his two Typhlosions in play. However his Discard Pile only has one Fire Energy card for him to use. Does that mean his second "Afterburner" Poke-POWER is used up, or can he use it later in the turn since nothing happened for the second one?
Since you cannot use an Ability for no effect, if the player only has one Fire Energy card in the Discard Pile the first Afterburner Poke-POWER may be used but the second cannot. So since it is not used up the player could use the second one later during the turn if a Fire Energy card somehow ends up in the Discard Pile.

Does Mewtwo's "Pressure" Ability block all of Tapu Koko's "Flying Flip" Attack's damage, even to the bench?
Pressure says, "your opponent's Active Pokemon's attacks do 20 less damage." Since it does not specifically designate Active or Benched Pokemon it reduces damage by -20 to each Pokemon that would be damaged by the attack.

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.

When can I use Scatterbug's "Abnormal Outbreak" Ability?
It's pretty clear. If you are not taking the first turn of the game, then when you get your first turn (i.e. the second turn of the game) you may use Abnormal Outbreak. This is the only turn of the game when this Ability may be used.

Does Goomy's "Sticky Membrane" Ability increase the attack cost of attacks where the cost is ignored, such as when "Roto Motor" applies?
No, it does not.

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.

The correct order for Milotic's "Energy Grace" Ability should be this: 1) Attach 3 basic Energy cards from your discard pile to 1 of your Pokemon (excluding Pokemon-EX), 2) Milotic is Knocked Out. That means you cannot use "Energy Grace" if you have no basic Energy in your discard pile, and you can't use "Energy Grace" to get back any Energy that are attached to Milotic.
