Have:
1x Dark Confidant (MMA)
1x Snapcaster Mage
4x Sphinx's Revelation
4x Thragtusk
1x Jace, Architect of Thought
Anything else on my trade-list

Want:
4x Mox Opal
4x Pact of Negation
Considering:
Glimmervoid, Leyline of Sanctity, Spellskite

I require Mox Opals most of all; I will consider trades with Mox Opals more highly than trades without them. (1 Dark Confidant for 2 Mox Opals is ideal. Also 1 Voice for 1 Mox Opal is something I would do as well)

Edit: I no longer require Caverns.

Sorry for double post, but I've updated the list and i no longer need the Caverns, and my VoR is gone.

I have an Opal and Pact.

Shoot me a trade if you're interested.
