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.

If Path to the Peak is in play and I play four Missing Clover to take a Jirachi {*} from my face down prizes, will I be able to use its "Wish Upon a Star" Ability?
Yes, you may. You are taking a Prize Card and the Ability is activated before it is in the hand or in play, so Path to the Peak does not stop it.

Can I search for any Pokemon VMAX or V-UNION with Adventurer's Discovery?

Can I play Plus Power or Electropower or Power Tablet on my first turn if I'm going first and am not allowed to attack?
Yes you can play those. Keep in mind there are some Pokemon (like Latios-EX with "Fast Raid" attack) that are allowed to attack on first turn.

If I have Hiding Energy or Snow Leaf Badge attached to my Active Pokemon, would my opponent's Leafeon VMAX's "Grass Knot" attack do any damage to it or not? If yes, would "Phoebe" remove the effect of Hiding Energy or Snow Leaf Badge for the damage calculation of "Grass Knot"?
The effects of Hiding Energy and Snow Leaf Badge are not blocking any damage from the attacking Pokemon, they are changing the stats of the Pokemon they are attached to. So they are not really affecting the damage done by Grass Knot; it is still 60x the Retreat Cost, but the Retreat Cost is now effectively zero. And since those cards are not affecting the damage being done (they're only affecting the Retreat Cost), Phoebe will not help it do more damage.

Can I use Heavy Ball or Level Ball to search for a Pokemon V-UNION card?
No you can't. Even if a Pokemon V-UNION has a Retreat Cost of 3 or more when it's fully assembled, you still can't search for any of the parts with Heavy Ball. And even though some of the parts don't have any HP listed, you still can't search for them with Level Ball.
