I haven't looked in depth at your deck just yet but I think you should look at the slope of your decks curve. It peeks at 3 and looks like a standard bell curve. Having a peek at 3 isn't really an issue in my eyes but I think the post peek slope should be more of a gradual decline instead of the steady step down. I'll do a break down of your creature selection soon

I pushed 6 cmc up before I posted it here, I can push 7/8 up, and remove some 3. I just was not sure how often his counters would get high. I will go through, and see if I have any more high cmc guys that are decent.

it doesn't have to completely rely on his counters. chances are some high cmc creatures will land in your hand at some point. Also in late games you will want higher drop more relevant things. also I personally really don't like Brutalizer Exarch maybe add a Bellowing Tanglewurm? Seedborn Muse also allows you to do tutors on your opponents turns which is awesome in Predatory Instinct if I hit seedborn and you don't shut it down I can win on my next turn for a 6 drop Thunderfoot Baloth makes even your low drops a massive annoyance. Avenger of Zendikar is another really nice creature generator for a 7 slot. Then the ultimate win con is Craterhoof Behemoth I know you mentioned a $10 budget but it is a serious game winner.

one last thing while im thinking about it I think your ramp level is a but too high. A ton of your creatures have built in ramp and you have 5 spells that put multiple lands in. You made need some outlets to justify the massive ramp say maybe a Genesis Hydra or multiple pumps of a Kamahl, Fist of Krosa? Kamahl also can discourage wrath effects by using your massive mana pool to man all your opponents lands

I love Kamahl. He is in my omnath deck. I accepted the more budget suggestions, and will look to get/trade for them. I don't have enough to trade for the $10+ cards, but I will look to get the others. Thank you.

I also figured the ramp would help feed the Safekeeper. He is one of my favorite creatures ever.

Yeva, Nature's Herald is pretty darn sweet in mono-green. I've got a deck running her as my general and she's an absolute blast to play.

I do like flash, and playing things when I want. I will give her a shot, she is really cheap, so worth trying.

Birds of Paradise is a good thing to search for when he plays his harp for one. I strongly recommend Contagion Engine because you can proliferate the counters on le Bard and kill their eardrums even more.

I got plenty of one drop dorks, and no birds left in my binder.

Contagion engine is a great suggestion. No idea why I left that out from the build, I have one that I am not using. Thank you.

If you are running all forests and no other lands Dungrove Elder might be cool.

He was in here initially, but my 3 drop was too crowded, and I like abilities. I run against so many board wipes, that he never sticks when I need him.

You have a bunch of creatures, why not run Beastmaster Ascension?

I do not have that card. I only dropped 10 bucks to make the deck, so did not really have room for it. That is a card that I am on the fence about because I like the secret threat. I don't like to have it all out there. It is something I am trying to change. Thanks for that one, it could really be a good add. Just gotta give it a try.

I like this a lot. Scryb Ranger was a really good addition. I wish I had a deck that played Hall of Gemstone, such a good card...

Dude, toss hall of gemstone in Sisay. You can get around it since it is only a 2 color deck.

Solid Deck, +1!

I already mentioned Cloudstone Curio, but Quirion Ranger would be nice, even though it's pretty expensive. If you could find someone to trade for it, I think it would help. That's all I can think of at the moment. If I think of any more, I'll get back to you.

Forgot about the Ranger. Thank you. I think I have one of those already.

Weird. For some reason I thought the ranger was like $5 or something. I didn't realize it was only $1. XD

Now that I know that, I think I'm gonna get one of my own.

Yeah, I am sure I have at least one in my box somewhere. Just gotta dig through it. Guess I overlooked it when I was getting stuff together. Thanks again.

Possible chopping block.

Tajuru Preserver has not been useful for me yet, but when I cut him is when I think I will need him.

Killer Bees now that I have the spiders

Fierce Empath really not needing them in my hand, but might keep,

Wildheart Invoker want to replace with kamahl

Yavimaya Elder never really want to grab him at the 3 spot.

Really need Scroll Rack, too bad that is out of the question. I know I have a Credit Voucher somewhere. Gonna try that out.

What about Unyaro Bees and Surrak, the Hunt Caller? They're both pretty boss in my opinion.

Hmm, Not big on the bees, but Surrak seems very helpful. I will prob be able to find him tonight. He is really good, thank you.

Other chopping candidates

Conjurer's Closet been too slow for me, just not getting use

Overwhelming Stampede with triumph, and kamahl, I will be good I think

Brutalizer Exarch slightly overcosted, erring on the side of keeping him in though.
