You should put some Soldier of the Pantheon in

Might want some Brave the Elements, and Precinct Captains in there. Check out my deck, it might give you some cool ideas.

BetaCow, it's a good card, but I don't have multicolored spells, and I have enough protection with instants to not have to worry about them. The only thing they'd be good for is the human synergy with Cavalry Pegasus and that's not good enough. But thanks for your input :)

claptonisgod, Brave the Elements is great, but not for a heroic deck, I could put a Shielded Passage in there over Brave the Elements ; and the Precinct Captain is great, actually. I definitely will test it out! Thank you! :)
