If Temple of Sinnoh is in play, does Double Turbo Energy provide one energy or two.
It would only provide one {C} Energy and would not reduce the Attack damage.

If I play "Canceling Cologne" and then somehow switch out the opponent's Active Pokemon, does the new Active Pokemon have its Abilities or not?
The effect of Canceling Cologne is on the opponent's Active Pokemon position rather than on the Pokemon itself. So if the opponent's Active Pokemon changes after Canceling Cologne has been played, the new Active Pokemon would have its Ability removed and the previous Pokemon would have its Ability restored.

If I play Phoebe while my opponent has a Dunsparce with "Mysterious Nest" Ability in play, do my Pokemon VMAX's attacks calculate Weakness if applicable or not?
The term "any effects" does not include effects that alter Weakness and Resistance. So Phoebe does not allow you to ignore Mysterious Nest's effect.

If you use Peonia and put a Treasure Energy or Dream Ball from your prizes into your hand, can you use the Treasure Energy or Dream Ball effect to attach it to one of your Pokemon?
Sorry, but Treasure Energy and Dream Ball only trigger when you are taking it as a face-down prize card, not when you are trading it with another card.

If I play Repeat Ball and choose a Pokemon that already has 2 in play and 2 in the discard pile, can I still search my deck for that Pokemon and fail?
You cannot search your deck since it is public knowledge that you won't find one because all four copies of the card are in known areas. If you have another valid target in play you must choose one of them; however, if you don't have a valid target the Repeat Ball goes back to your hand.

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.

If I have Alcremie with the "Additional Order" Ability in the Active Spot and then play Cafe Master, does my turn end immediately if I retreat Alcremie?
No, your turn does not end because Alcremie was active when you played Cafe Master.

When Welder is used to attach 2 Fire energy, does Old Cemetery trigger once or twice?
Any energies attached from the hand would trigger Old Cemetery, once for each energy card being attached. So in this case you would put 4 damage counters total.

I have 5 Pokemon on my Bench, and 2 of them have the "Omega Barrier" Ancient Trait. If my opponent plays Avery and I choose the 2 Pokemon that have "Omega Barrier", do they get discarded or is the effect of Avery blocked?
Yes, they get discarded. The discard effect of Avery is on you, the player choosing the Pokemon, not on the Pokemon with Omega Barrier.
