Deck was a tad too slow when fighting a G/W human deck. I stopped playing boros after the berserker from M12 cycled out...

Check my deck out for play testing or just ideas in general!

To Arms! The Enemy Approaches!

I find Mikaeus, the Lunarch too slow. I would suggestion trimming creatures and using more 4-ofs for consistency. I would fold Mikaeus, the Lunarch into Lightning Mauler , and then drop Gore-House Chainwalker into Nearheath Pilgrim and Zealous Conscripts (to make him a 3-of). The only other thing I might suggest is something other than card:Devil's Play, perhaps Thunderous Wrath . At its worst, it is the same cost for a 5 damage card:Devil's Play, at its best it is (R) for 5 damage.

I like the suggestions but prefer to wait at this time to see how it works tonight at my FNM. I may make some changes depending on how it does.
