If you really like Defenses, Temple of the Dawnbreaker might be a nice addition.
http://www.cardgamedb.com/index.php/magewars/mage-wars-card-spoilers/_/core/temple-of-the-dawnbreaker-coreIn my FM I run the following:
For armor: Stormdrake Hide; Dragonscale Hauberk; Rhino Hide
For health regen: Regrowth Belt, Regrowth, Vampirism
First tier protection: Forcefield
Last ditch protection: Force Orb, Force Sword
In my opinion and experience, armor and health regeneration are typically better than stacking defenses, especially in the long run. Defenses don't always protect you whereas armor and heath regeneration are always helpful. Additionally, here are a lot of unavoidable attack spells that can completely undermine all of your defenses. Plus, all the opponent needs to do is put Falcon Precision on an attacker and your defenses suddenly become useless. Long story short, I don't recommend relying too heavily on just defenses. Lastly, I rarely use Dancing Scimitar as a defenses because I like to play very aggressively and use its attack as much as possible.
