I had stopped playing right around the time of Urza's Block and didn't keep up with the game for years. Right around the time of Lowryn I got a wild hair to play again and discovered the Gatherer. As I was perusing all the thousands of cards I had missed I discovered Autochthon Wurm.
Pretty straight forward. Ramp out lands and Eldrazi tokens to pay for the Wurm. The ten colorless can be taken care of quickly by tapping and then sacrificing five Eldrazi tokens. Serra's Blessing allows you to take advantage of the Wurms huge toughness on the defense. Higher Ground and Favor the Mighty give you a fairly impenetrable wall of Wurms.
