I'd be worried about running out of summons, but maybe our metas and playstyles are different?
I really like how the spell Fortified Position interacts with creatures with 0-1 armor, and feel like it could be good for Skeletons. I can appreciate if you're trying to run 0 Enchantments and just making all of your opponent's Dispels useless.
I usually want access to some armor for my Mage, favoring Dragonscale Hauberk and Leather Gloves. (I like Eagleclaw boots for my feet, hence no Leather Boots.) I also like a way of regaining life like Regrowth Belt or Death Link.
