Stonescar Aggro is hardly the most innovative deck idea, but I've tuned this and been pretty happy with the result. Some specific card observations:
Bloodseeker - this card in many ways is the primary draw to Stonescar for me, because it gives you two credible one drops that stay on the board, and with all of the Hunt cards running around this can grow to a 4/5 in the late game.
Catalyze - I only play 3 because I hate drawing 2 - this is supposed to be an aggro deck after all. But getting Double Damage on the right card can flat out win you the game.
Grove Supplier - I honestly don't understand how this isn't an automatic 4 of in every aggro deck. Giving +1 attack to every unit is huge, and there is virtually no downside.
Twilight Lantern - I am seeing more of this card on the ladder, which is not surprising because it is fantastic. Remember, not just night triggers it - it can also be triggered by hunt getting you the Advantage card, the Cylix - many things. Excellent two drop.
Ziat, Steelwarren Reeve - so amazing. Often will get the one card that can save them from their hand, and the downside is really not very significant, especially for an aggro deck.
Raniya, Miviox Maniac - I really like this card, but I didn't want to play three 4 drops, so I put it in the Market.
Comments definitely welcome!
For the time being I just slapped The Big Wheel In there for the time being.
