You have a pretty low curve- I honestly think you could take Attune with Aether completely out of the deck, even though it did provide energy for the Bristling Hydra. I would rather replace it for adding in more Cast Out and Aerial Responder. Try adding a few more low CC aggro cards like Rhonas's Stalwart

I tend to agree, I think I'd rather have the Channeler Initiates than the Attune with Aether and sideboarding out an Aether or two didn't seem to have much of a negative effect when I played it today. I'm thinking Renegade Rallier to make the Scrounging Bandars more effective.

I've also been considering dropping a Fan Bearer. I often get him out early and half the time he sits there doing nothing. I wouldn't take him out completely but I think he'd do better as a 2-of.

It can be really seen that this is your first deck, but really not bad for one.

Yes absolutely take out Fan Bearers card just isn't good enough.

Kujar Seedsculptor Just isn't good enough too, there are just so much better cards.

Appeal / Authority Is too situational in my opinion, of course when you are ahead it can be amazing, but when you are with empty board against control it is dead card rest of the game probably.

Then what to get in when you take out so many cards...

Renegade Rallier Is solid card if you have good ways to get revolt, so more of them.

Last Bristling Hydra would be nice.

Longtusk Cub Is very strong card but then you should take out other 2 drops which means some of your mana dorks.

I don't really see need to mana dorks anyway in this deck, you don't play anything very big to ramp on.

Then you want more removal, you have only 3 Cast Outs. Skywhaler's Shot Would be pretty nice addition to this deck in my opinion.

But first, get good manabase it is just so important to get right mana

And d*mn 24 lands is way too much when you play only one 5 drop in your whole deck, i would play like 20 lands maybe 21 maximum.

And get those Attune with Aethers out of the sideboard :D

Sorry if i sound too judging my english isn't too great, i don't try to be mean.

Thanks for the suggestions!
I like Skywhaler's Shot. I was using a pair of Fairgrounds Wardens but having a body was tough. I'll swap 2 for the Fan Bearers and probably get some more for the sideboard.

I'm not sure about the Longtusk Cubs though, I think I'd rather have a counter from a Kujar Seedsculptor on an Aerial Responder or a Scrounging Bandar than a Longtusk Cub with 2-3 counters. I know the Sculptor isn't great by itself, but it just has more synergy with what I'm trying to do.
