To search forest and empty your deck by lands, you can add Everbark Shaman or Seedguide Ash . So you can pump your best card Dungrove Elder .

If you build an "only creatures deck" you can consider to add Ghoultree (with rancor is very dangerous!), Lumberknot , Orchard Warden (gain life, but it's to expensive), Sapling of Colfenor (to gain life and to draw!), Unstoppable Ash (wonderful: you can pump your other treefolk, you can champion Treefolk Harbinger to serach again a forest or another treefolk when it come back to play), Weatherseed Treefolk (very dangerous), Wickerbough Elder (to destroy artifact or enchantment)

Might I suggest card:Nature's Lore? It would help you ramp some and/or help Dungrove Elder . I am also a little bit concerned about your lack of turn-one plays. Most casual decks I play against it isn't good to get behind on your first turn. Maybe consider an Arbor Elf or similar card to help ramp up to your 3-drop Treefolk on turn 2. Having 3 mana turn 2 is a great advantage and I find myself putting cards like Arbor Elf in almost every green deck I build because of that. Pretty good overall, though! Looks fun.

@decapablo i like your ideas and might make a spinoff of this deck utilizing some of the cards you mentioned. thanks very much!

@remyth i hear you on the turn one drops. unfortunately treefolk only have one card with a cmc of 1. and id prefer keeping this deck with its "tree theme." normally i would have either Arbor Elf or Llanowar Elves in a deck like this like you mentioned i should include. thanks for the input!

I would throw in Vines of Vastwood .

if you're worried about flyers you can always sideboard something like Raking Canopy which kinda fits the whole tree theme. haha

I've always liked Coat of Arms better than Door of Destinies . Coat of Arms changes more, but is sooooo much quicker at boosting (even with being more mana). Just a thought, and I love the idea of the deck.

Coat of Arms can help your opponents as well though, remember that.

That is true, though if you are running a tribal it is more likely to help you more. Anyway, its really a personal preference.

i have a few copies of Coat of Arms but i always sideboard it and occasionally throw it in when im not playing a zombie, elf or goblin deck because then i would more than likely be defeating myself.

Raking Canopy is DOPE and ill have to grab a few copies for my sideboard. if i get 2 of those out that stops most flying creatures. the fact that it fits my theme makes it that much better

I suggest that you either remove Dauntless Dourbark or Dungrove Elder , and then throw in Cloudcrown Oak . You should check out my deck "Roots and Twigs"
