High priorities for me right now would be picking up a few more copies of Geist of St. Traft, and a playset of Sphinx's Revelations.
Filling out my play-sets of dual lands would be my secondary goal, so that would be:

1x Blood Crypt
2x Temple Garden
2x Clifftop Retreat

Anyways, check out my profile and if there's anything juicy, let me know :)
