I'm in the process of finishing up UWR Delver and need a few of the smallish cards.

2x Grafdigger's Cage
1x Meddling Mage
2x True-name Nemesis
2x Arid Mesa

On the same note, I'm currently borrowing some of the dual lands. I'd be willing to discuss purchasing these. I need:

3x Tundra
1x Volcanic Island
