Valakut, but no Scapeshift (an Extended deck from MTGO)

JWay made it to 16th place in the most recent MTGO PTQ with a Valakut deck that caught my eye by dint of having no copies of Scapeshift.

Rather than trying to Scapeshift into an instant win, this deck attempts to Transmute into one or more Valakuts as well as a Prismatic Omen to make all of your lands into Mountains. This changes the deck from a combo deck to a control build with a slow-burn win.
