BOROS BURN is a Standard deck I've been running with for a while now -- with quite good results overall! (i.e., several 4-0's and 3-1's in MTGO Standard events, several 1st places in local FNMs, etc -- I haven't had a chance to play any high-level events with this one, yet.)
The key to this build is its strict adherence to the "Philosophy of Fire". This means that almost every single non-land card in the deck including its creatures is, functionally, a burn spell. I recently moved the 4x Eidolon of the Great Revel to the main specifically for this reason, despite the fact that in general having fewer creatures equates to "Virtual Card Advantage". There are just so few match-ups where the Eidolon is bad in the current meta.
However, the fact that the deck is often a "Draw-Go" deck makes playing it almost feel like a control deck (especially combined with the lifegain... which helps with the self-damage from the Eidolons and lands). Indeed, against aggro and creature-based midrange decks, this is a control deck!
How does burn maintain control?! By exiling or charring any creature that's a serious threat, and by attacking your opponent's life total so directly and so rapidly that they are forced to play a different game than they intended. By turn 3 or 4, they'll think twice about any effect that involves paying life -- be it a Thoughtseize or an un-tapped shock land! From there, by playing carefully and correctly, it is never too difficult to seal the deal.
(NOTE: Cards listed in the "maybe-board" are, with few exceptions, things I'm considering for the sideboard -- NOT the main deck! If the card is already included in this deck list, then the number given is what I'm considering for somewhere in my 75, in addition to the number in the deck currently. Also -- I've mostly just included this stuff so I can keep track of, and remember, it all!)
