I don't know how much I would like to have card:stoneforge acolyte in this deck. It's just an ally trigger of CMC 1. I would rather play Cliffside Lookout as the extra toughness isn't really that relevant, or maybe even make a 2/2 split with Kor Bladewhirl and Cloudshift or any other piece of interaction that you like.

Having a turn 4 casting Kor Bladewhirl + Reckless Bushwhacker can be overwhelming as chumpblocking is going to be extremely difficult.

Yeah, I'm not sure either about the acolyte. The one thing I noticed is that you have 9 green mana sources with 4 coco's; that might give you some issues. Other than that, it looks good. You should have enough one drops to use bushwhacker on turn 3-4. It's a pretty quick deck. Keep up the good brewing!

I don't know how useful AEther Vial is in this deck, since the surge cost can only be paid for cast spells. Maybe trade it in for some removal, cloudshift or other Allies?

I think it's the other way around, Reckless Bushwhacker and Akoum Battlesinger get stronger as we get more creatures into the battlefield favouring the use of vial, besides the new adition gives us another reason to leave vial in 3 along kabira evangel and firemantle mage. Those 2 extra power in a haste creature can be game winning even if we can't cast it for its surge cost.

Surge cost also gives more value to our one drops in the late game, what do you do with a second vial in midgame now? nothing, now you can at least dump it and cast bushwhacker for more value.

Ally Encampment is also another reason to run vials now since you can bounce your creatures and vial them in again.

I've found Ondu Cleric to be a lot more effective than Lantern Scout (especially if you have Jwari Shapeshifter... have gained 30 life in a turn against fish and burn on a few occasions).

I'd also consider adding in two Captain's Claws, it is a great play on turn 3. A lot of the decks that don't run AEther Vial use Hardened Scales, so that's another to think about (although it isn't one of my favorites).

(The deck I'm using with comments is at WurG Vial Allies.)
