I have a legit one.
Most dueling leagues that I know of allow .08 arreats face since it's not really overpowered (.09 is better in most circumstances), and arreats isn't that rare so there much more legit ones floating around that you might expect.

/w *thesuck for duels.
I use only legit but will be happy to take anyone on 1v1 in a friendly duel =)
