Edit: While the deck might not be awful in other matchups it is terrible vs control. There isn't enough early aggression to warrant thermo + stormchaser and there are too many counterspells.

Back to Blue/Red with more horror synergy and different spells

Run Spell Shrivel to replace Void Shatter if I don't buy void shatter

Niblis of Frost vs Bedlam Reveker (Horror)

Thermo-Alchemist vs Ingenious Skaab
