A new Dialga and Hero’s Medal has been revealed from S3a Legendary Heartbeat! The set will be released on July 10th, however the cards will likely be revealed later this week. Thanks goes to Arantxa T. for the translations!

[M][M][C] Flash of Destruction: 130 damage. Discard 2 Energy from this Pokemon.
Weakness: Fire (x2)
Resistance: Grass (-30)
Pokemon Tool: Attach a Pokemon Tool to 1 of your Pokemon that doesn’t already have a Pokemon Tool attached to it.
The maximum HP of the Pokemon VMAX this card is attached to is reduced by 100. If this Pokemon VMAX is Knocked Out by damage from an opponent’s attack, they take 1 less Prize card. You can’t attach this card to a Pokemon if it would be Knocked Out upon attaching it.
You may play as many Item cards as you like during your turn (before your attack).
