Those trainers O_____O
Gold Remover is clearly an ACE SPEC, it would be stupidly overpowered if it wasn't.
Mysterious Pendant seems insanely broken. It basically makes something with 90hp or less invincible. Either mistranslated or someone wasn't thinking when they made it. It would basically force every deck in the game to run Tool Scrapper because you would never be able to kill the thing.
If Desert Resort isn't an ACE SPEC, that could be pretty interesting. 1 damage adds up fast, the issue is playing against opposing fighting decks.
Same with Decolora, although the no special condition thing is AWESOME. Due to the OHKO nature of the format I'm not sure how much healing 1 damage is going to matter, but if the format ever slows down it could be decent. It unfortunately doesn't really work in Blastoise because that needs Tropical Beach to function.
