If I play Captivating Poke Puff and find a Pokemon with the Omega Barrier Ancient Trait in my opponent's hand, can I choose that Pokemon to be benched or does Omega Barrier block the Captivating Poke Puff?
Yes, you can put that Pokemon onto the Bench. Ancient Traits are only active when that Pokemon is in play.

If I use Evosoda to evolve my Basic Pokemon into a Stage 1, can I then use Wally to further evolve it into a Stage 2 on that same turn.
Yes, but be careful of the order in which you play the cards. Wally says you can use it on a Pokemon that was put into play this turn, but Evosoda says you cannot use it on a Pokemon that was put into play this turn. So you can play Evosoda first then Wally, but you cannot play Wally then Evosoda (on the same Pokemon, of course).

If I have a Pokemon-EX with Head Ringer attached to it, what happens if I use Ninja Boy to swap it with a non-EX Pokemon?
Since it is no longer a Pokemon-EX the Head Ringer would get discarded.

Can I play Professor Kukui if I have no cards left in my deck?
Yes you can, because you still get to do the +20 bonus damage for your Pokemon's attacks.

If my Yveltal with "Fright Night" Ability gets KO'd, am I then able to use Exp.Share on one of my Benched Pokemon to recover one of Yveltal's Basic Energy cards?
Sorry, but no. Fright Night would still be working so Exp.Share would not enable before Yveltal hits the Discard Pile.

If Darkrai attacks with "Abyssal Sleep", can Pokemon Ranger clear the effect of flipping 2 coins when Asleep?
Asleep, Poisoned, etc. are Special Conditions, regardless of how many coins you need to flip or how much damage the poison condition does. Therefore they are not altered by Pokemon Ranger.

If I used Mewtwo's "Barrier" attack last turn and this turn I play Pokemon Ranger, does that clear the effect so I can use "Barrier" again this turn?
No, Barrier does not "place an effect" to prevent its use on the next turn (unlike attacks such as "Volcanic Heat" which says "this Pokemon" cannot attack next turn). Instead, the attack does a Game State check to see if it was used last turn. Since there is no effect to clear, Pokemon Ranger won't allow you to use Barrier two turns in a row.

Let's say I have Machop active with a Focus Sash attached, and my opponent's Mewtwo-EX uses "X Ball" for 360 damage with four Double Colorless Energy and a Muscle Band attached. The Focus Sash leaves Machop with 10 HP remaining. If I then use Ninja Boy to switch Machop with Pidgeot-EX and then use its "Mirror Move" attack, does Pidgeot-EX do 360 damage in return?
Yes, it would. When using Ninja Boy the amount of damage done last turn is remembered by the new Pokemon, so Mirror Move would do 360 damage to your opponent's Active Pokemon.

If I have Volcanion EX in play and I use its "Steam Up" Ability, can I then use Ninja Boy to switch it with a different Volcanion EX and use "Steam Up" from the new Volcanion EX?
No, that won't work. Even though the new Volcanion EX is a different Pokemon than the first one, it remembers the Steam Up ability was already used this turn so you cannot use it again on that Pokemon.

If a player with Exp. Share on a benched Pokemon has discarded their Active Pokemon and its attached energy due to KO from an attack and already promoted a new Active Pokemon, have they missed the opportunity to use Exp. Share?
Promoting a new Active Pokemon takes place after the knockout, so at that point it would be too late to use Exp. Share.
