Trade with Heartbreaking Cards of Staggering Genius

I recently completed another trade with Matt over at Heartbreaking Cards of Staggering Genius.  I sent him some Topps Kimball minis, and he helped me get a little closer to my Platinum Diamond goal:

That brings me to 93 out of 330 for the Series 1 Platinum Diamond set - it's definitely looking like a long-term proposition if I'm going to get them all.  Thanks for the trade Matt!
