Since you have Temple Bell and other draw abilities I would splash some blue and add Sphinx's Tutelage to mill them for a win con. I would also add Leyline of Sanctity to give yourself hexproof and like everyone else is saying Isochron Scepter would work beautifully in this deck.

There fantastic and I believe there pretty cheap as well.
Actually I would also replace the 2 Jace Beleren for Jace Memory Adept. The 0 ability would work a lot better for this deck.
Actually from everything I'm seeing it is still legal in everything except standard.
