Considering Malistaire is Death School, having Life Attacks would be more efficient. Do not be mistaken that Life doesn't have any strong attacks. As I said many times about Malistaire's minions...Life Blade + Centaur = Dead.
You dont seem to have many zero pip spells in your deck. Try adding blades and some life attacks. Don't just rely on your fire traps to increase your damage or else you are toast. I would also add wyldfire or sanctuary to your deck. Plus guiding light goes great with dryad.
