Cavalry Charge Upgrade

As the name implies, I want to upgrade the "Cavalry Charge" Precon deck. I don't have it quite yet since I only just got back in town, but I've done some good research on it. I already have a general list of cards to maybe include, such as these:

[[Steel of the Godhead]] [[Spirit Mantle]] [[Unquestioned Authority]] [[Armored Skyhunter]] [[Reconnaissance Mission]] [[Coastal Piracy]] [[Bident of Thassa]] [[Marshal of Zhalfir]] [[True Conviction]] [[Arna Kennerlid Skycaptain]] [[Knights Charge]] [[Cover of Darkness]] [[Banner of Kinship]] [[Haakan, Stormgald Scourge]] [[Invasion of New Phyrexia]] [[Glory]] [[wonder]]

That said, I'm worried about target removal. I don't know how many/if any are in the deck, and also just want to get to know some more cards. I usually play Temur, so Esper is pretty different from what I know(that being "Unga bunga!" with blue draw), and want advice. Care to help me out guys?
