The name of the yoyo is the “EKG” Not the “Slayve”. There was a “Slayve I” edition of it, because the anodization finish was inspired by Boba Fett’s ship in Star Wars, the “Slave I”.
To answer the OP’s question, Train Wreck’s are discontinued. SPYY won’t be making anymore. They do have the Train Wreck 2 , but that’s pretty different than the original. Your best bet is to do like the others said, and get one off the B/S/T.
