If it were a structure deck they may also be reprinting the cards from Blackstorm rising. But it's probably a minibox with these cards as supplementary R cards. If there's any SR or UR blackwing cards added they probably didnt change the rarity as the guy above me said
My prediction is Gale The Whirlwind would be released as the UR and a Blackwing Synchro as the SR. But since it is mini-box you still need to reset just to get more than one copy of the SR
