Borzhov Exalted (Standard)

Rush exalted, attain bitches, profit.

Seriously though, the best thing about this deck is the huge early damage, and ability to pick and choose their blockers. Stromkirk is very strong early since most 1- or 2-drop creatures are Human. Slam down a Madcap Skills and he grows massively and is even harder to block. If Stromkirk isn't doing the job (usually only when they aren't playing humans), Knight of Glory gets past most Zombie decks and Knight of Infamy gets past any other white dudes that aren't human (angels, etc). Plus, having Angelic Benediction to narrow down their blockers even more AND give exalted is amazing. Even if you're attacking with a Knight of Glory and all they have is a Deathrite Shaman, tapping it means it can't use its abilities to gain life or deal damage, which could possibly be overlooked by your opponent when calculating damage.

Also, one thing that is very commonly overlooked about Exalted is that it lasts until the END OF YOUR TURN. This means that in your second Main Phase, using Essence Harvest can be devastating. Even if your creature is blocked (which is usually pretty uncommon anyway), being able to Essence Harvest for huge amounts is like giving your creature unblockable and lifelink for 3 mana.

Overall, I've done pretty well with this deck, coming in second many times at my local FNM (but never first T.T).
