Please help us tune my buddy's BW warriors aggro build! We've been working on it for months, and trying to get it ready for Game Day this wekeend.

It took 4th place in a 5 round tournament last night after losing in the finals to a red aggro deck, and overall red aggro indeed seems to be its biggest weakness. This deck is normally the aggro / beatdown, but it just can't match the speed of a good red build. Given how well red aggro performed at the pro-tour I want to make sure that our game plan against it is rock solid.

It has excellent midgame against just about everything -- Blood-Chin Rager and Arashin Foremost are really the rock stars of this deck. We like how Blood-Chin Fanatatic combos with Blood-Soaked Champion, but we're considering cutting back on the Fanatic in order to add another Sorin and another Butcher's Glee or another Secure the Wastes. So far those cards are incredible together, and Sorin's +1 ability is just absolutely incredible after going wide on the field. Return to the Ranks is just a stellar card given our low mana curve, and does a wonderful job of helping us recover from Crux of Fate and End Hostilities.

So far it performs very well against everything except for red aggro. How would you side-board against that matchup?
