After vigorous playtesting, i've made quite a few changes to this deck to not only make it cheaper, but much more effective as an aggro deck.
First off, I've done away with the fatties:
-1x Bloodfray Giant
-1x Chaos Imps
-2x Rubblebelt Raiders
-1x Molten Primordial
These cards costed too much mana, and there were much better creatures that have a lower CMC. Thanks to cyrilpang and user:JakeSlytherclaw7 for the suggestions that led to this decision!
I've also taken out one Splatter Thug because I found that they were a bit too common in this deck and I wanted more room for smaller creatures.
After taking out the six cards mentioned above, I have chosen to replace them with the following smaller, more efficient creatures:
2x Rubblebelt Maaka, mainly for the bloodrush (who doesn't love extra damage output!)
4x Riot Piker
Riot Piker is, in my opinion, an AWESOME addition to this deck. The fact that it has first strike makes it a very dangerous threat when pumped up with a Madcap Skills or soulbonded with a Stonewright. This card really contributes to the speed and power of this deck, attacking each turn and often forcing your opponents to chump block to avoid taking further damage.
As always, feedback and suggestions are greatly appreciated!
