 {Boros Reckoner} that card slows aggro down is a card that needs to be removed, it's excellent if it is in your budget.

Same goes or shock and check lands if they are in your budget, unfortunately, lands make such a difference

 {Lightning Mauler} should replace bomber corps. Also I find that  {Legion Loyalist} is very bad in 4's. Maybe try  {Doomed Traveler} to add more evasion.  {Thalia, Guardian of Thraben} could be a good side board card or even main board to slow down control decks.
