The idea is simple, charge toward destruction!
LOTS of ramp in here from the simple Elvish Mystic up to Nissa, Worldwaker and Primeval Titan. On the tail end of things I have the big 3 waiting to be unleashed: Emrakul, the Aeons Torn, Kozilek, Butcher of Truth, and Ulamog, the Infinite Gyre.
A good beginning hand will look something like Elvish Mystic, Sakura-Tribe Scout, Ancient Stirrings, Nissa's Pilgrimage, Lay of the Land and two Forests. With this starting hand it's easy to have 6 mana open by turn 3 to spend on a big beater.
Use Lay of the Land early to fetch a Mountain in preparation for Signal the Clans. This card is your best friend, allowing you to fetch 3 creatures that could help you most at any given moment (think about CMC and enter the battlefield effects). You'll only get one in hand with the other two being buried on the bottom of the library, but its a great deal in my opinion.
Use Ancient Stirrings to fish for more lands to slap down at an ungodly pace with Sakura-Tribe Scout or grab an All Is Dust if you're getting swarmed. More times than not, this will disrupt whatever your opponent has planned for you and allow you to keep whatever colorless creatures you have out at the moment.
Nissa, Worldwaker fits so well in this deck because she can help considerably with ramp, but a HUGE plus is her other +1: turning lands into 4/4 elementals... that are COLORLESS!
Thanks in advance for any suggestions and please +1 if you like!
