"The most interesting and worrisome development was the 1st-place finish of a Tezzeret/Thirst/Thoughtcast deck at Ovino X." - The deck is TezzCast, and
was developed back in 2008.
Other than that, I agree that the Power 9 Challenge is one of the best things to happen to online Vintage. At least for me, as I bought into online Vintage one year ago, but never got to play with the cards until that event was announced.
