My server had crazy luck.. We've had a hashi pull, 4 minatos (hokage, no jonins) and an edo deidara. I've gotten an edo deidara and a minato.

On the flip side, spending 2k coupons and expecting a 400 dollar ninja seems like not a good idea. Rly dont think you should pull for the super duper rare as that'll just lead to disappointment. Pull for all the other crap and if u get lucky, then hell ya
