Valakut, the Molten Pinnacle is a very powerful card.  So powerful, in fact, that it was on the initial ban list for Modern.  Why was it so feared as to be on the same list as Hypergenesis, Skullclamp, Umezawa's Jitte, and Golgari Grave-Troll?  The answer is Scapeshift.  When you combine the two cards, it creates a very consistent win condition.  But how to tie the deck together, that is the question.  Easy, Cryptic Command!
