Man, I love this deck. So, after doing a mono-green playtest with my deck and four other mono-green decks, on turn 8, I was able to attack for 104,310 (that's right, over one hundred thousand) trample damage. Ahh, the possibilities.

Seedborn Muse , Tooth and Nail , and Chord of Calling are all good for any EDH deck with green.

Looks like a really fun deck. +1 from me.

is illegal in this deck. The color identity of him is green/black, and your general is mono-green.

Good call. I didn't really look at him close enough to notice that he was black as well. My bad.

Druidic Satchel maybe?

I would say, put the vorinclex into the deack and have Azusa, Lost but Seeking as the general. I am a firm beleiver in cheap generals. But this deck i'd say is still pretty tough.

Not enough lands to make her the general and I would have to remove a lot of what make the deck work to make room for the lands. Thanks for the suggestion though.

amm this deck still running? Triumph of the Hordes ?? well you got some creature that puts tokens.....

oh i did not see it.... my bad sorry (_ _")

Predator Ooze maybe, Primordial Hydra definitely, and how funny would it be if someone played a Tunnel Ignus on turn 2?!

last time i checked Primeval Titan was banned sadly..such a great creature.

I should probably keep up on that. Thanks, perseas24!

yeah i recently made a Sisters of Stone Death edh deck and i had both primetime and Griselbrand in it../facepalm

Love the marquee

Mimic Vat + Eternal Witness ?

Penumbra Wurm ?

Citanul Hierophants

Have you considered adding Omnath, Locus of Mana ?

Do you think Somberwald Sage would have a place in this deck? It can be fragile but can help with drop big creatures fast.

Have you considered Primordial Sage, with that much land pull the only thing left to draw into is creatures which leads to more creatures

I'd suggest Thunderfoot Baloth over Roughshod Mentor because although the boost requires you're commander in play, I find the +2 bonus gives that bit of reach.

I hate to break it to you, but Chameleon Colossus is technically an Elf. Just sayin'.Maybe replace it with Heroes' Bane?

I find myself wondering why you don't have a Craterhoof Behemoth in your deck, as it's a wonderful finisher. Also, Praetor's Counsel is a lovely card for green!

I like the look of this list, I run a pretty similar list Omnath, Locus of Forests with a different commander in Omnath, Locus of Mana however i do sometimes switch to Vorinclex, Voice of Hunger depending on how competitive the envoronment is and how much of a dick i want to be at the time... I prefer Omnath though, he is just sweet. I also personally think more lands are needed. i playtested a few times and using the Vancouver Mulligan rules found that i was constantly having to mull for more lands, but depending on what your group does this could be the right number for you.

I Dislike Rites of Flourishing in your list as well as Heartbeat of Spring i would replace them with Exploration and Zendikar Resurgent not quite as good, but helping your opponents out is not something i like doing in EDH espeically with Vorinclex, Voice of Hunger i feel like you are just giving them more outs.

Suggestions from your maybeboard:

Blighted Woodland is really nice ramp (I run it in my mono-green) because it still produces mana the turn it comes in, but can ramp you when you get to it. Hydra Broodmaster is a favorite of mine because not only does it live up to "STOMPY!!!", but it can also be "STOMPY AND FRIENDS!!!!!". Also Sol Ring tends to be good in any deck, though green is less dependent on it I think your deck could benefit from it due to the higher nature of your curve.

All in all, a good decklist, +1 from me!
