So I'm at a bit of a weird point financially and I can pick up a Snapcaster Mage and a Jace, Architect of Thought from my local shop or I can just get 2 Jace for a little cheaper. My shop has trouble holding both cards for any more than a day, so I plan on going in tomorrow and picking up one of those combinations. So what I wanted to know is: What's better for my UW control deck? I don't have either, for the record. Thanks in advance for any help?
