I spent some time working on Shardless this week, and I'm increasingly of the opinion that trying to get around Red Blasts by cutting blue cards (especially Jace, especially against Miracles) is probably not a good plan. They're bringing the blasts in to fight Vision, and having fewer targets makes it much more likely that those Blasts get their intended targets. I'm taking the Blohon route and boarding a Jace now, along with a Clique.
