Introduction
It's pretty clear that players (and Wizards of the Coast) have divergent opinions on the role of data in Magic. My opinion is that data is an imperfect representation of reality. I would much rather have as much data as possible, while understanding the limitations of such data. That said, I think we have reached a point where we as a community might be oversaturated with these weekly reports and the conversations that follow. Ryan and I are both committed to collecting Vintage data from as many sources as possible. What we remain split on is how often to disseminate that data. We could continue to publish weekly reports or we could combine them into monthly reports like this one. Please chime in the comments below.

Metagame Breakdown
Xerox is what we are using to refer to former Gush decks - most are Young Pyromancer based, either with Delver or splashing white for Mentor. Some are playing Seeker of the Way... Fish decks refer to Bug Fish, Combo is kind of a grab bag for DPS decks - most combo decks have been absorbed into Paradoxical. Tom's winning Rector Flash list is the source of the 87.5% MWP on 9/23.
Thanks to Ryan for his considerable help as usual. Jonathan Suarez also helped with data collection for the 7-23 challenge and it was much appreciated.
