Don't bother with the Terraformings, Commandant > Terraforming. All of the time. : U
Fusilier is bad, you can probably go to 3 Necrovalley. Cat is not particularly good; I understand you want to search your Skill Drain, but I don't entirely like its consistency. You could probably fit a Gravekeeper engine and/or Royal Tribute in there if you cut Cats. The latter is especially devastating if you've summoned your single monster in hand already (since your deck is so monster-light).
