I'm looking for some cheaper rare cards from ROE or other cheap rares from Zen block like scute mob. Hopefully you have some of those to trade for the skullclamp.
Bear Umbra, Keening Stone ,Hellion Eruption, Repay in Kind , Near-Death Experience ,Splinter Twin. From what I can see these cards go from 50 cents to just under $2 a card. Skullclamp is listing in the $1.50 to $2.99 range. Skull clamp is such a great/broken card. I have it in my artifact deck along with many other banned/restricted cards. Its such a broken deck :-D
