New Server SinX need help

[mauiii]

I just started fresh in mid-rate server 99/70 around 5 days ago..
The server doesnt have any donation item like wings god items and etc..
I've got myself 3 characters - WS,Champ and SinX
WS for vending, Champ for MvP and SinX for PvP and WoE 
What I need to know now is EQUIP for my SinX because I've already got a Dopplegangger Card..

What are the equips for me to give my SinX a good damage??
And what more cards that I should find??
And please tell me about the stats and build too..

Your help is really appreciate..
