It doesn't seem like there are a huge number of auras in the set, if that's supposed to be a theme. There's also a fair number of equipment (especially at rare - whereas there are no rare auras [+1 global enchantment]).
Just as importantly, putting a cost reduction mechanic on a 5 mana creature isn't very helpful. In Limited, I would probably play it as a 5 mana 5/4, & I really wouldn't care about the effect. On a common, an Aura Gnarlid esque effect might be good.
