Suggestions for Thief Card Set Gear please?

[Neuneck]

A +8 double critical Paper jur would suit your needs best. With a regular Jamadhar [1] you won't reach enough crit to make the paper card worthwile.
If you're looking to wear the set as a sinX only, you can look into a wool/tidal combo. The combo is hot with it's +10% hp...
Else, Manteau and Boots are fine, too, i think.
