Not a huge fan of the mystery boxes. I like seeing them opened on YT channels but they are mostly duds. Busting a single box is difficult enough. A random assortment of packs is really tough - especially when you're paying up for a chance at a big card.
I loved opening 2019-20 SPA when it was 130USD per box. I even hit an inscribed FWA and a Black FWA in one box. They were both duds. The inscribed was Matt Roy from the KIngs and the Black FWA was Ryan Kuffner who was already an UFA when I hit him. I did hit Suzuki, though. That was a nice pull. Great design.
Maybe call UD and see if they have a Brannstrom FWA lying around.
