I wanted to try proliferate with some Arcbound action, despite my limited cards in the latter area. I am hoping that a couple Serum Tanks and a Drafna’s Restoration will help me out with card management, but I may need more. The Quicksilver Behemoths are better than I expected, but I am loath to take 4 for fear that they come up too quickly, especially since they are among the (currently) 11 cards that require blue mana. I may still need to go more blue with Echoing Truth to combat flat-name decks that use a lot of tokens, but we’ll see. It has a 7/16/2/7/3/2/3 curve, for an unacceptably high 3.03 average cost, but ideally the Silver Myrs and the Urza’s lands should get me rolling a little quicker.
