The "Alpha Growth" Ancient Trait says "When you attach an Energy card from your hand to this Pokemon... you may attach 2 Energy cards." Does that mean I get to attach one additional Energy card or two additional Energy cards?
You only get to attach one additional Energy card, for a total of two cards attached at that time.

What happens if Kecleon with "Color Change" and Wobbuffet with "Bide Barricade" end up as Active Pokemon opposite each other? Does Kecleon change to Psychic, or does Wobbuffet shut off its power and Kecleon stays Colorless?
If Kecleon starts out as Psychic and then Wobbuffet becomes Active, Kecleon stays Psychic. But if Wobbuffet is Active first, or if they both become Active at the same time (including as the starting Pokemon), then Kecleon stays Colorless.

If I have an opponent's Pokemon Tool F card attached to my Pokemon-EX, does its effect stop working if I evolve into Togekiss with the "Bright Veil" ability and make it my Active Pokemon?
Bright Veil only affects the play of an Item. That means the act of playing it. If it is already in play, enabling Bright Veil has no impact on it. It will stay in play and keep doing what it is doing.

If my opponent has Togekiss with the "Bright Veil" ability Active, does that prevent me from attaching Pokemon Tool F cards like Jamming Net or Head Ringer to their Pokemon?
No, Bright Veil does not prevent you from attaching the Pokemon Tool F card to your opponent.

If I use Kyogre EX's "Smash Turn" or Celebi EX's "Wind Whisk" or Gengar EX's "Dark Corridor" attack, can I switch it with my benched Sigilyph that has the "Safeguard" Ability?
Since the attacking Pokemon is the target of the switch effect, Sigilyph can be moved in this situation.

If I or my opponent have Goodra with "Slip Trip" in play, can I still attach a Team Flare Tool to my opponent's Pokemon?
Yes. It does not prevent a player from attaching a Tool to another player's Pokemon.

If I attach a Rainbow Energy to Eevee, what Energy type does it count as for "Energy Evolution"?
Rainbow Energy is not a Basic Energy card. It will not trigger the Ability.

Say I attach a Water Energy to Eevee and do "Energy Evolution". I want to find a Glaceon but unfortunately I only have a Vaporeon in my deck. Do I have to attach the Vaporeon to Eevee?
No. Any search for a specific card or type of card in your deck can be "failed" at your option.

Will Eevee's "Energy Evolution" ability still trigger if it has an Energy attached to it while it's affected by a Special Condition?
There is no text on the card to say it's shut off, so it still works even when afflicted by a Special Condition.

If Eevee only has 10 HP left and Frozen City is in play, would it be KO'd before I have a chance to use its "Energy Evolution" ability by attaching a Basic Energy?
No, it would not. All triggered effects have to be resolved before checking for KO's, so you would take the +10 damage for Frozen City first, then use Energy Evolution to search your deck. Of course, if you fail the search and Eevee's damage is greater than or equal to its HP, then Eevee is KO'd.
