Modern Twelvepost: Not Even Once

"Josh Rayden has enjoyed mild success on the SCG Open series, with Top 8 and 9th place Legacy finishes. He has played Magic since Ice Age and worked for Pastimes, Inc., the Premier Tournament Organizer out of Chicago for three years. A dedicated Eternal fan, Josh recently finished 10th at the 2011 Vintage Championships.

This week he brings us a slew of videos and a Twelvepost brew for this weekend’s Modern Pro Tour in Philadelphia. Convinced of the deck’s nimble brute strength, he believes it’s the deck to beat."

From the videos (and writeup) posted, it seems that this deck can do some absolutely absurd things unchecked, especially with the inclusion of Amulet of Vigor. From the article:

"The things that Amulet of Vigor allows you to do are certainly the most impressive.

Turn four double Primeval Titan? Sure, no problem.

Turn five double Primeval Titan and Emrakul, the Aeons Torn? Easy.

How about casting Scapeshift on turn four off of four Forests and then casting Primeval Titan and Tooth and Nail with entwine on that very same turn? Not only is it possible, you can do with with 6 mana left over!"

Thoughts on this? This deck seems pretty resilient and quick... what're people doing as a plan against this deck? What just crushes it?
