Scholomance Spell Damage Mage

I'd really like to try out a Spell Damage focused Mage list once Scholomance hits. Unfortunately, I'm already missing Astromancer Solarian and Kalecgos. Might craft them if I get lucky with the new legendarys, they look strong enough to be of use in Standard and Wild.

Not sure if 4 Dragons are enough. What do you think?
