This question has to do with Layers, which can sometimes be very complicated. Fortunately this one is simple. If you want to read all about them, you can do so here.
When applying continuous effects, generally the most recent ones will overwrite older ones. Since Life and Limb 's effect is the most recent, it will overwrite Awakener Druid 's. The forest will be a 1/1.
What happens if I have an Awakener Druid and Life and Limb in play? For instance, if I play Awakener Druid on turn 3 and then Life and Limb on turn 4, will that revert the 4/5 forest creature created by Awakener Druid into a 1/1 creature?
Example: Awakener Druid has entered the battlefield, and my opponent's forest is now a 4/5 green treefolk creature. He then enchants it with Rancor and ends his turn. I proceed to play putrify, and destroy his Awakener Druid . Would Rancor be destroyed and put back into his hand, or would it stay attached to the land?
I think you'll find that Awakener Druid , Blanchwood Treefolk , Bog-Strider Ash , Cloudcrown Oak , Crabapple Cohort , Heartwood Treefolk , Oaken Brawler , Old Ghastbark , Sentry Oak , Sheltering Ancient , Weed-Pruner Poplar , Edge of the Divinity , Seek the Horizon , and Carapace aren't going to work very well. (14 cards)
Consider the following list of cards: Nemata, Grove Guardian , Yew Spirit , Adaptive Automaton , Coat of Arms , Mirari's Wake , Steely Resolve , Descendants' Path , Elvish Soultiller , Creeping Renaissance , Primal Command , Demonic Tutor , Explosive Vegetation , Sensei's Divining Top , Cultivate , Rampant Growth , and Skyshroud Claim . (Note: this is 16 cards.) While this isn't as strictly creature oriented as the current deck, it maintains a concrete treefolk theme while cutting virtually useless cards and supporting the good treefolk creatures you're running.
Could also do like these in the form of Druids/Elves: Awakener Druid ,Birchlore Rangers ,Centaur Rootcaster ,Citanul Hierophants ,Citanul Woodreaders ,Thriss, Nantuko Primus ,Thelonite Druid ,Seton's Scout (for flavor haha),Quirion Druid ,Nantuko Cultivator ,Krosan Restorer ,Elvish Pioneer ,Elvish Branchbender ,Civic Wayfinder
Not sure how you want it man but I just like giving suggestions :]
I see a few problems with this deck just from glancing at it.
You have no way to defend yourself early game. none. Getting land out is always nice, but you need some way to defend yourself while doing it.
-There are plenty of cards you can use to do this, like Elvish Pioneer , Sakura-Tribe Scout , Skarrg Guildmage , and Awakener Druid .
It looks like almost all of your mana ramp is from your hand. That isnt a bad thing, but it has problems in the current iteration of your deck.
-you need more ways to put land in your hand. All I see right now it Mulch
I would suggest cards like Crusher Zendikon , Gruul Turf , Journey of Discovery , or Gatecreeper Vine
Thats all I can think of at the moment, I hope I was helpful :D
