I think the set is really cool and brings some cool ideas to the table but I think entrench would be better if it had a way to make your guy attack again. Also the Jace you designed is really cool but the second ability feels a little well too powerful for blue. i hope that wizards sees this and takes some of your ideas into consideration or asks you to help them in the future because this set is really cool.
