I wish NR Mages had spell synergy/tutors. I'd love to see NR-specific cards that could tutors spells, feed off of spells played throughout a match. The mage archetype is really mediocre at best, and I'd like to see it buffed. 

It feels kinda insulting when NG can tutor neutral tactics(glorious hunt, DECREE, garrison, etc.)that work with Helge, a nutty engine,  and also gain leader value with enslave from neutral cards, but spells have no way of being tutored from the faction that could build a potentially strong mage archetype. Switching a card like Dethmold into a spell tutor instead of this awkward mage-swarm boost effect comes to mind.
