I think the new Jace will be a lot better when Innistrad comes out, and Conley Woods tries to find a way to make a U/B Dredge deck that randomly top 8's a PTQ. I think a Jace mill deck will do decent until the rotation, when Tome Scour, Archive Trap, and Traumatize leave. Then it's price will drop for a bit, and then Innistrad will be released and he'll be amazing.
