Casual Encounters: "Drafter's Dream" challenge

My two friends who I often play Magic with have decided to do regular deck challenges. My friend created the first one, entitled "Drafter's Dream," and the constraints are as follows:

Deck = 40 cards
Land = 18 lands
Creatures >= 1
Enchantments >= 1
Sorceries >= 1
Instants >= 1
Artifacts = 0
Amount of a single card <= 2
Color in deck = 1
Amount of different sets = 1

Basically, pick a set, pick a color, and create a 40-card deck with those restraints. I don't have many cards, and I used to play mono-green. So, here is my creation using M11:

2x Llanowar Elves
2x Sylvan Ranger
2x Garruk's Companion
2x Awakener Druid
2x Elvish Archdruid
1x Protean Hydra
1x Gaea's Revenge
1x Fog
1x Plummet
2x Giant Growth
2x Naturalize
1x Cultivate
2x Overwhelming Stampede
1x Primal Cocoon
18x Forest

I'll report back once we've had a chance to play.
