Ridiculously long posts are fun!
aszl826 -- you might want to post what format you want the deck help in. Those above me have posted help for dueling decks, in a type 2 environment. I, on the other hand, have advice for a multiplayer deck that laughs at the frivolous "typing" of decks.
Keep in mind that this is a creature heavy deck, which plays heavily to a diplomatic crowd. I will describe why I choose cards, then number them in a more legible way.
Multiplayer Green: An Option
Vine Trellis -- good card, mana and cheap blocker.
Squallmonger -- good card, allows everyone to kill pesky fliers.
Hunted Wumpus -- fun card, makes many allies.
Invigorate -- good card, makes allies with ACC.
Avatar of Might -- fun card, you have it, show it off,
Hunted Wumpus might set conditions for its ACC.
Silverglade Elemental -- medium creature, fetches land.
Night Soil -- too many people play reanimation in chaos games, narrow their choices with Night Soil!
Creeping Mold -- good for general removal.
Tranquil Grove -- can't be beat for multiple enchantment removal.
Rancor -- better in duels, it still makes for fun in chaos games (play it on prospective allies' creatures).
Spore Frog -- useful creature, a living Fog.
Gaea's Blessing -- play with your graveyard, almost as good as (but more versatile than) Regrowth.
Mirri's Guile -- one of green's few library manipulation card, highly recommended.
Forests -- a definite must have.
Jolrael, Empress of Beasts -- animate the lands for the kill, just WATCH YOUR BACK!
Avoid Fate -- common instant from Legends, after errata, it allows you to counter target enchantment or instant targeting one of your permanents. VERY useful when playing against blue.
River Boa -- cheap islandwalking regenerators are always useful in chaos games.
Llanowar Druid -- to untap all forests...
Man-lands -- actually, any non-forest green mana producing lands can save you if you encounter those Wake of Destruction/Acid Rain kind of players.
There, some of my preferred green cards and why I like them.
To make it more readable:
Creatures 24
4 Vine Trellis
4 Hunted Wumpus
3 Silverglade Elemental
3 Squallmonger
3 Spore Frog
3 River Boa
2 Llanowar Druid
1 Jolrael, Empress of Beasts
1 Avatar of Might
Spells 17
4 Invigorate
3 Gaea's Blessing
3 Rancor
2 Avoid Fate
2 Creeping Mold
1 Night Soil
1 Tranquil Grove
1 Mirri's Guile
Land 20
16 Forest
4 The green 3/3 man-land (I forget the name).
Not as fast as some decks, but if you explode in a chaos game it only makes you a large target very quickly. There are enough alternate mana generators and small creatures to keep you one step ahead of other colors, and the Gaea's Blessings prevent decking yourself. And you have enough big guys to pound on people.
That's it. Again, please specify what kind of help you are looking for. Thanks for the exercise in deck-building, though.
