Part One: The Simic (Standard Legal)
I've discovered some really nasty things you can do with the Simic. Take Cloudstone Curio and Coiling Oracle, for instance.

To get back lost land, use:

Now for a decklist:
Lands:
12 Forest
4 Island
4 Novijen, Heart of Progress
4 Simic Growth Chamber
Creatures:
4 Coiling Oracle
2 Azusa, Lost but Seeking
2 Primordial Sage
2 Meloku the Clouded Mirror
2 Simic Initiate
2 Carven Caryatid
2 Cytoplast Root-Kin
2 Sakura Tribe Elder
2 Ohran Viper
Enchantments;
1 Honden of Life's Web
4 Doubling Season
Artifacts:
2 Cloudstone Curio
2 Spellbook
Instants:
2 Thrive
1 Chord of Calling
Sorceries:
2 Commune With Nature
2 Kodama's Reach
In the end: Start by using Coiling Oracle (with Cloudstone Curio), Kodama's Reach, and Sakura Tribe Elder for mana acceleration. Later, summon Meloku, and use his ability to create a token swarm, and power them by Novijen (keep Simic Growth Chamber intact!)- this is several times as lethal when you have a few Doubling Seasons in play! Not only are there at least twice as many, they are twice as powerful!
