Did 100 spins, got masked man by 80. Things with the highest drop rates would the purify protection runes, seal frags, and coupon*20. Also got deidara decent number of times (6 I believe), so apparently you can nab a few frags of him. Definitely still don't suggest trying to get all of deidara here though. Note that me getting masked man in 80 was pretty lucky on my part.
