I just got the whole set in, and the Atomic I got has a ball that's basically stuck in place. Man, that sucks. The blue Spriggan Requiem does look really good in person though, and it pairs up nicely with that deep blue Destroy too.
Still trying to figure out what these "mold differences" are supposed to be with Lost Longinus and Sieg Xcaliber though. Comparing the originals and the booster versions, I'm really not seeing much of a difference.
Cincinnati-based Organizer, and owner of every single currently released TT Burst bey part in at least one color. Hard to think of anything I don't have from MFB either...
