I am new to MTG and to this site. My question is this. Is there a way to post my inventory and if so are you guys willing to give me some ideas on what cards to use in my deck based on the few cards I have? This would be very helpful.

yeah post the link to you page, and make your inventory public

Here it is!

Hmm. You don't have very much yet (I'm pretty new, too :) ). I do like using Chasm Skulker. Encrust and Divination are nice cards to have. You got a Jace, and he's not exactly the best Planeswalker right now, but it's something. Maybe make a blue and something else deck for fun?

Yeah I have been using blue and black but I don't come close to beating any of my friends lol.
