So, this tournament was a blast. I hadn't played Vintage seriously for years and this event was refreshing and fun. The staff and players that attended were awesome, to say the least. I'm not going to do an official tournament report, so I figured a brief follow-up here isn't too out of line.
20 dedicated Vintage players showed up with their best decks and fought for a Workshop. From what I saw, the field looked like it had a number of the following:
shops decks (terra nova, Martello, Metalworker all represented)
NWCS
Merfolk
BUG aggro
UR delver
GWx hate bears
steel city vault
Grixis control
More interesting was that Dredge and Oath were underrepresented. I didn't see either archetype. Unfortunate for me, seeing as how I played a pretty standard Terra Nova pile with 3 cages maindeck. >.< Personally, I went 3-2 overall, not making top 4 in a 5 round swiss. Oh well, I had a stellar time playing cards, even if all 75 were proxies.

Anyways, the format is happening here in Minnesota! 20 dollar vintage tournament every third Saturday of the month at Hi-Score Games and 10 dollar vintage tourneys every Monday night at Monster Den. I'd encourage anyone who loves the format and can make it to the area to attend!
