Hisuian Heavy Ball has been revealed from the twin sets Time Gazer and Space Juggler, which release in Japan on April 8th. We expect many of these cards to join those from Battle Region in our May set, Astral Radiance!
Look at your face-down Prize cards. You may reveal a Basic Pokemon you find there and put it into your hand. Then, shuffle this Hisuian Heavy Ball into your remaining Prize cards and put them back face down. (If you don’t reveal a Basic Pokemon, put this card in the discard pile.)
You may play any number of Item cards during your turn.
