The Theme Decks in Legendary Collection were the first to include a special 61st card, a random reverse-holographic card from the main set. Wizards also did this with the e-series Theme Decks.
Unlike Theme Decks before, Turmoil was the first to include three rare cards.
The non-holographic versions of Dark Blastoise and Dark Raichu are exclusive to this deck, as they only have holographic versions in the main set. However, this version of Dark Blastoise can be found in the Team Rocket set, while Dark Raichu can't be found anywhere else.
