So far, you're good, but the big problem as I see it is that you don't want Blessing on your Scorpions because Adrenaline works better, and you don't want adrenaline on your Cockatrices unless they're already blessed.
On the other hand, if you swap the Cockatrices for Horned Frogs, you have two different Adrenaline-ready creatures. At that point, you could practically remove the Light entirely and still have a royally badass deck -- just add 2 more Adrenalines, 3 more Emerald pillars, and fill it out with more Scorpions and Frogs.
