more Call of the Conclave Selesnya Charm . you might want to add Thragtusk !

Do you think the mana ramp is ok? And what should I take out to put in Call of the Conclave and Selesnya Charm ? Annnnd, why Thragtusk ?

i think that you have enough ramp i think that you should consider dropping 1 card:Cathars' Crusade for the conclave call, and thragtusk because it is really good and if they kill it, ou get a 3/3 beast that you can populate, the life gaining is too bade either.

Ya, I suppose card:Cathars' Crusade is more of a bonus than a necessity.

What do you think about that? I put Thragtusk on the side.

After playtesting a bit, I feel like the deck needs more finishers. It kind of durdles with 1/1 Humans and 3/3 Centaurs, albeit a lot of them. I think there are too many mainboard populate cards which are too specific, namely Growing Ranks and card:Druid's Deliverance. I'd suggest going all out with 4 Parallel Lives , adding as many Thragtusk as you can afford mainboard (any card which gives you 5 life and then a token after it dies should go in every midrangey green deck), putting Garruk, Primal Hunter mainboard, another Armada Wurm or two, editing your mana base, because all the colorless really screws over Arbor Elf , and maybe splashing black for Lingering Souls and Sorin, Lord of Innistrad . 3-4 Intangible Virtue s should probably be mainboard too.

Also full playset of Wayfaring Temple s. Populate plus parallel lives is amazing, and maybe consider Silverblade Paladin (plus Rancor )for the synergy with TWO populates with the temple.

So, I added Birds of Paradise to replace Arbor Elf . I'll look into the other suggestions.

I'm trying to make it a early game win not mid game. That's why there's very few big guys and more little ones that increase a ton with populate.

Well, unfortunately the birds aren't in standard. If you are trying to go for an early game win, tokens isn't the way to do it, at least, not with Growing Ranks , Parallel Lives or card:Trostani, Selesnya's Voice. Those are distinctly mid game cards, because they don't affect the field until after the fourth turn, and you should be hoping for a win swing on turn 4 or 5. If you want an early game aggro deck, go with Silverblade Paladin s, Rancor and Wayfaring Temple s. If you want a mid to late game win, keep the Growing Ranks and Cathar's Crusades and Trostanis.

Ok, great point. I'm looking into it and retooling.

I'm not sure what to take out in order to add more Parallel Lives , Armada Wurm , Garruk, Primal Hunter , Thragtusk , and Wayfaring Temple .

My thought for the deck was to have a bit of control in order to get creatures and tokens out and populated. That's why I like card:Druid's Deliverance and Growing Ranks .

Also, I'd like to figure out how to add more card:Cathars' Crusade I feel that this could be devastating.

If you want control, you'll have to add a color, like blue or red, for some Azorius Charm s/Supreme Verdict (which may not have too much synergy) or Searing Spear /Mizzium Mortars action. When the term "control" is used, it tends to mean dominating the board via removal and tempo, two things which green and white aren't too great at. Instead, it seems like you are looking to ramp to some big stuff so you can drop some bombs to make your little guys all great. You could maybe look at including Farseek s and maybe some card:Ranger's Paths for some ramp, so things like card:Cathars' Crusade aren't so slow to cast, and maybe ramping to a Craterhoof Behemoth would get you the finish you want.

Right now, I feel like the only problem with the strategy is that there are tons of fast decks that will get in before your populate stuff gets going, or there will be control decks which will board wipe before you can do enough. At least, in so far as being pretty competitive. Maybe take what you have now, and just try it out on Cockatrice or at an fnm (which I would recommend more).

take a look to my deck:http://tappedout.net/mtg-decks/selesnya-tokens-splash-black-1/

I think Growing Ranks seems to be a very good card but it doesn't. Try playing 4x Parallel Lives , 2x Garruk, Primal Hunter and 2x Garruk Relentless  ^Flip in your main. lots of tokens, a little bit of control using 2nd ability of Garruk Relentless  ^Flip and a finish combo taking out all loyalty counters. and like TheArcticWind31 said, you have to add another color.

also you can search in your library for Armada Wurm sacrificing a token.
