Congratulations! Those are some great goals, and maxing out Foundations cards is pretty inexpensive unless you're looking for a gold deck. I maxed mine out some time back, it was great! I do need Conclave summoners badly, I'm playing Modern basically with Foundations cards and summoners. Reward cards from Conclave have helped and some of the old Rebellion ones as well.

Great luck with those goals, It will get you into gold!
