You definitely want Fabled Hero in here. The double strike is just too good not to pass up. I'd also recommend mainboarding the Gods Willing you have in your sideboard. Pro any color of your choosing can be a life saver, and the scry is nice too. I'd also say try and run 2-3 copies of Legion's Initiative . The boost is gives can help you win faster, not to mention it is great defense against board wipes.

Hope these suggestions help.

You could drop one Boros Charm and one Titan's Strength for two Legion's Initiative so you have three of all your instants. You still will have a good chance to draw them even though the will be down to three each.
