I think that the strongest aspect of this deck is the way that it deals with creature removal. All of the effects that are strong in this deck are spread out amoung multiple creatures. For example, Alesha, Who Smiles at Death, Bramblewood Paragon, and Brighthearth Banneret cannot all be taken out by one spell, however each introduces a new strategy that you can use against your opponent.
Going through each individual card and its applications in this deck...
1. Narnam Renegade: Good turn 1 drop if you have a fetch land. Playing a 2/3 Deathtouch (and hopefully trample from Bramblewood Paragon!) is never not going to be good I don't think. Narnam can get brought back by Alesha, Who Smiles at Death, although in most situations it's not the best card to bring back.
2. Vampire Lacerator: Truthfully, I wish there was a better card to play. I find myslef consistantly underwhelmed by the Vampire Lacerator, and I think that Narnam Renegade is a better turn 1 drop IMO. If someone has a suggestion for a replacement for it, that would be cool. I am considering only running 2 of it and then throw in 2 Fatal Push, or even a pair of Inquisition of Kozilek.
3. Brighthearth Banneret: Great card, and is probably your best turn 2 drop, as it is either going to get rid of some removal from your opponent's hand, or you're going to have a super efficient turn 3. It also has a reinforce effect, which can be handy sometimes if you have some open mana, as having 2 of these is not good, there are many better cards for you to play over a second Brighthearth Banneret. This is one of the core cards of the deck.
4. Bramblewood Paragon: Another great card, +1/+1's are always useful, and every creature in your deck is a warrior. I would play a Brighthearth Banneret turn 2 over this, which is a toss-up for a lot of people, but in my mind, attacking with your Brighthearth Banneret isn't going to happen anyway. In general, I don't like to attack with Bramblewood Paragon, because it is a high priority target for your opponent.
5. Blood-Chin Rager: Funny card, love the way it interacts with Alesha, Who Smiles at Death, because people never expect that to come back (especially if you discard it with Bloodrage Brawler!!). This guy gets a lot of damage to your opponent's face.
6. Bloodrage Brawler: 4/3 for 2, what's not to love? Granted, you DO have to discard a card, but if you have Alesha, Who Smiles at Death, pitching a Blood-Chin Rager or a Vampire Lacerator means that they'll get brought back in, and effectively have haste. If you don't have Alesha, Who Smiles at Death, this card certainly isn't as good, but between having an empty hand (which does happen frequently if you have a Brighthearth Banneret) and having a second copy of Brighthearth Banneret, you don't come across many situations where it's unbearable to discard a card.
7. Fanatic of Xenagos: Great card, lots of value, and often has haste. It's a good addition to the deck.
8. Alesha, Who Smiles at Death: An interesting card that counters removal well, makes Bloodforge Brawler not a burden to run, and survives combat often due to first strike. I think it's a pretty solid card, but it becomes a big target for your opponent's removal.
9. Madrush Cyclops: I only run 2 of these because it's pretty situational. I find that if you have Brighthearth Banneret out, its a good turn 3 drop, because if you have a surplus of 2 drop creatures in your hand (all of which are purposefully one colorless and another mana), you can empty your hand turn 4 and get a decent amount of damage in.
10. Dismember/Lightning Bolt: Removal.
