Hello.
So first, I would remove the
Mana Confluence. You don't need them because you are only using cards that cost White or Black mana. More
Plains and Swamps will be fine.
I don't really see much use for
Tormented Hero. The Heroic trigger can only be used four times in your deck, due to
Defiant Strike. To me, it really doesn't seem all that useful.
So, while I think your deck needs some work, I think it has potential. Good luck with the deck building.
