Deck review

You're topping out at 4, so I feel like 23 land is too much.  You can probably go down to 21-22. 

You're not getting hardly any synergy out of burning tree in this deck. Scavenging ooze is all your playing at the 2 drop level that can hit off it.  I feel like you need the flint hoof bores to go with BTE.    Lotleth synergy with scavenging ooze, but how's it playing for you otherwise?  Have you tested it out? 

one drops, you need the exp 1, or stromkirk nobles.  I don't know if you have access to thundermaw's but you could go on the kibler plan and do elf into bigger drops. 

Overall, I think you need to decide if you're going to keep the 2 drops the way they are.  That's where the deck appears to need work the most. 

Also, take a look at this RG list, it's similar to where you're at, but has a more focused mana curve.  This deck placed 7th at worlds.

I'm not saying copy it exactly, but you can analyze it more.  It needs to be able to go up to 6 mana, so it has 24 lands and ramp.  It wants to be able to consistently play thundermaw on turn 4 and hellrider turn 3.  Burning earth in the side is a strong card against control and some midrange decks.  Just something to think about when you're building your own deck.
