Beastite from SM12 Alter Genesis has been revealed in V Jump magazine! Thanks goes to Bangiras for the translation!
Pokemon Tool: Attach a Pokemon Tool to 1 of your Pokemon that doesn’t already have a Pokemon Tool attached to it.
The attacks of the Ultra Beast this card is attached to do 10 more damage for each Prize card you’ve taken to your opponent’s Active Pokemon.
You may play as many Item cards as you like during your turn (before your attack).
This is only the third card revealed, despite the set’s September 5th release date.
The card features a new illustrator. Presumably the item is a hunk of rock from Ultra Space (hence the “-ite”).
