Giacomo

No, I didn’t remember the name Giacomo either. Checking Bulbagarden, it turns out he was the DJ from Team Star’s Dark crew, who wishes anyone else would call him “DJ Vice.”
But it’s a name that’ll stick in TCG player heads if they’re wont to use Special Energy in their decks. This Trainer card forces an opponent to remove such an Energy from every one of their Pokémon in play. He’s there to combat the Reversal Energy that’s being added with this set, that acts like the Scramble Energy card from EX Deoxys back in 2005, gifting the Pokémon it’s attached to three Energy of all types so long as it’s a Stage 1 or 2, and has no rule box. That’s daft powerful, so Giacomo will be pretty useful in combatting it.
But also, I love this art by Kiyotaka Oshiyama, previously best known for the Charizard vs MewTwo VSTAR promo in the infamous Charizard Premium Collection box. The angle is so interesting, the out-of-focus light rigging in the foreground, as we see him checking his set list in front of his decks.
