Sulfuric Vortex
Pulse of the Forge
Manabarbs
A very straightforward RG Beatdown list, with an aggressive creature curve (5-5-1-3-1) and efficient burn to remove blockers and provide range. Two gamebreaker enchantments that fit perfectly were used as finishers: Sulfuric Vortex and Manabarbs. Except for these enchantments (a tech that has been used before), the plan is the same as always: curving 1 and 2 mana creatures to put on pressure and keep it for as long as possible. Then, sit back and sling burn at the opponent.
This build was quite consistent but had the recurring problem of RG aggro - struggling against early defense and life gain. Since it burns its resources so quickly, it's easy for RG Beatdown to run out of fuel if they are not carefully managed. This list has a better than average "gas tank", though, falling back to Pulse of the Forge, Siege-Gang Commander, Fireslinger, Magus of the Scroll and Fauna Shaman after the first attacks have been performed.

Blaze
A simple yet very effective BR Aggro-Midrange deck made of 19/23 creatures and 4/23 removal spells - limited taken to its bare bones. The mana curve is high, peaking at 4 and 5, meaning the deck wins by attacking slowly and relentlessly, instead of overrunning the opponent with tempo like dedicated aggro decks.
As is usual of BR Midrange, a suite of 2-for-1s (Nekrataal and Shriekmaw) combined with must-remove threats (Ob Nixilis, the Fallen, Jiwari, the Earth Aflame, Fire Servant) grind down the opponent, forcing him to use 1-for-1 removal while you play your 2-for-1s. This strategy worked great against aggro, since it simply outclasses the aggro deck's creatures after the first assaults. Against classic control, though, the creature removal is not so effective, the most problematic threats will be countered, and, most importantly, mass or repeatable creature removal will be devastating.
