A new Item, Flint, has just been revealed from SM6a Dragon Storm! The set will release in Japan on April 6th! Thanks goes to WPM for the translation.
Discard 2 cards from your hand in order to play this card.
Search your deck for up to 4 [R] Energy, reveal them, and put them into your hand. Then, shuffle your deck.
You may play as many Item cards as you like during your turn (before your attack).
Interestingly, Flint is the name of one of the Elite Four members in Sinnoh. It’s therefore quite possible that the English name of the card will be changed in order to avoid confusion!
