Abilities » Chromashift | Trainers » Old Cemetery
If Kecleon has no Energy attached and I attach a Psychic Energy to it when Old Cemetery is in play, will Kecleon's "Chromashift" Ability kick in before checking for Old Cemetery or will Kecleon get 2 damage counters?
Old Cemetery's effect will happen first, so Kecleon will receive 2 damage counters.

Trainers » Big Parasol | Attacks » Red Banquet
If my opponent uses Guzzlord's "Red Banquet" attack and my Active Pokemon with Big Parasol attached gets KO'd, does my opponent get to take an extra prize for "Red Banquet" or not?
Big Parasol prevents all effects of attacks from your opponent's Pokemon done to your Pokemon; but taking an extra prize is a game effect, not "an effect done to your Pokemon", so your opponent gets to take the extra prize.

Abilities » Dedechange | Abilities » Shadow Box | Trainers » Team Magma's Secret Base
Say Team Magma's Secret Base and Mimikyu with "Shadow Box" Ability are both in play. If I put Dedenne GX on the Bench, can I use its "Dedechange" Ability or will it be blocked because it has damage counters on it?
Since Dedechange and Team Magma's Secret Base are simultaneous effects, it is up to the player to choose the order in which they will be applied.

Trainers » Cheryl
When I play Cheryl, can I choose not to heal one of my Pokemon that only has a few damage counters on it so I can avoid discarding the Energy attached to it?
No, there is no choice. All of your Evolution Pokemon that have any damage counters on them will be healed and have to discard their energy when you play Cheryl.

Trainers » Wally
Wally says "you can use this card on your first turn or on a Pokemon that was put into play this turn". Does that mean I can use Wally on the very first turn of the game when I am not allowed to play Supporter cards?
No, Wally does not override the game rule of the player going first not being able to play Supporter cards on their first turn. You can only play Wally on your first turn if you are going second.

Trainers » Heinrich Eich
Due to an error in naming the German version of the card for Samson Eich (aka "Samson Oak"), the name of this card will be changed. The original name for this Supporter card was "Samson Eich". The card name must be changed to match the original name of the character, which should fall in line with the animation and video game series. The new card name for Samson Eich will be "Heinrich Eich".
Trainers » Gewöhnliche Angel
Due to an error in the German version of the card text for Gewöhnliche Angel (aka "Ordinary Rod"), the first part of the card will be changed. The original text for the Item card says, "Wähle 1 aus:" ("Choose 1:"); the new text for Gewöhnliche Angel will say, "Wähle 1 oder beides aus:" ("Choose 1 or both:").
