It would be helpful if you told us the following: 1. What Level, as already asked. 2. What school are you playing. 3. What gear do you have, including Wand and pet. 4. Are you doing 1v1, 2,v2, etc. 5. How is your deck setup, do you have hits in the sidedeck, etc.
If I knew that, maybe I or someone else could have some suggestions.
Just my opinion, but I didn't see very many other responses to your posting. Based on your gear, you don't seem to have very much resist, and therefore you will have to play like a glass cannon, to some degree. Duelist has been down, so I cannot see what deck you are using.
Based on the gear, ring and athame, I would suggest that you enchant all your hits and put them in the side with any needed TC's. Use the main part of the deck for defense and heals, if you have a Amulet. You will need to be aggressive in each match, digging hard for the card you need.
I expect you have Tower, weakness, the -70 shields for Fire and Storm learned.
If you playing passive, then you have to gain resist.
If you want to play a few matches, I would be willing, I have an Ice and Myth with basic gear at level 50. I do all of my PvP at level 120, but so I may be a little rusty at the lower levels.
