These are great lists. I will just mention "blight", since no one else has yet. I like that one.
I also like Claymen, since I can take them into the water early on.
I'd like to see lower-level and more eclectic spells get cast more often, but even though I would "like" to cast them, I often do not, because I feel they are not competetive for their gem cost.
Once I reach that research level, I find myself casting the same old stuff over and over again, because it is "worth it" (Ghost Riders, Send Horror, Wrathful Skies, etc.).
