As one can see I built this deck to be extremely aggressive. It's got a lot of potential combo's, an ideal field would be to have a bloodsoaked champion, grim haruspex, butcher of the horde, rabblemaster, and Athreos out. butcher is your heavy hitter and ideally you can at least give him haste by having a sac outlet the first turn you get him out. Both rabblemaster and champion accomplish this, and are also renewable resources. Also ideally your opponent can't block butcher due to his flying. it's possible to have a turn 4 hit for 5 damage, in addition to lifelink and vigilance if you do it right. Given the support of utter end and hero's downfall, you should be able to deal with their heavy hitters, big defenders, and planeswalkers as well. The pain lands are sure to hit your health early game, but with 3 copies of sorin, and another sided the life gain from him alone should be enough to offset the pain lands and more. Atheros is also great for recycling your sac outlets and putting pressure on your opponent to pay the life to keep your creatures in the grave. Given this doesn't matter as much with rabblemaster generating a token every turn, and bloodsoaked champions raid ability. Elspeth is great if you're falling behind a bit because her -3 is a great field clear to hit your opponents power cards. the best part is wingmate roc, atheros, zurgo, and your weaker creatures such as tokens and champion all survive meaning that you can use her to decimate your opponents field while keeping some of your most powerful cards in play and ready to deal out massive amounts of damage. Sarkhan is pretty inherent to why he's so great in the deck, but i'll elaborate anyway. Worst case he comes out, kills one of their stronger creatures and barley lives, hopefully long enough to start dealing out damage. Best case you get him out, +1 him and swing immediately with a 4/4 (hopefully unblockable due to his flying) dragon. The deflecting palms are a great way to defend yourself from damage early game, or to trick them into dealing massive damage to themselves late game. By themselves against the right opponent played at the right time they can be a game ender, and are thus exceptionally useful. Obviously there are other combo's, tricks, and synergies that this deck can and has accomplished, but I've described the core of what it is ideally supposed to do. Try building it yourself, making your own edits, or leaving suggestions in the comments box. Now go fourth and kill them all, and take their wallets!
