The Day 1 Field of a Grand Prix is always a mixed bag. The good and the bad are out in varying proportions, and until eight rounds of swiss can determine the successful, it's pretty much anything goes. Today is no exception. Netdecks and homegrown concoctions appear with equal frequency.
Three decks stand out from the crowd, nonstandard enough to be unexpected, but not so rogue as to be played by only a handful. In no particular order, they are:
Earning new popularity thanks to Morgan Douglass's Top 8 performance at New Orleans is one of the format's most explosive decks: Mono-blue Tinker. Between fast starts, silver bullets for many decks, and the Big Ups to take care of mid-range control, it's no wonder that players should be rediscovering their love of this deck.
Just yesterday at the Trial I watched a player get locked under Mishra's Helix on his third turn, while his opponent had enough mana left over to start working his Planar Portal. That sort of unfairness doesn't let itself go on very long. The lack of sideboard hate out there today could give Tinker a big edge. Sligh decks that left their Rack and Ruins at home will find themselves ill equipped to handle a Crumbling Sanctuary.
The Descendents of Fiends
Endorsed by Worlds Top 8 Competitor Ken Krouner, this blue-green deck has been mostly ignored in favor of its ultra-aggressive counterpart. Against an aggressive field, though, its River Boas, Walls of Blossoms and Calls of the Herd can prove bigger than the expected, buying time to set up the lock. Against slower decks, though, it seems like it needs to ramp to a quick Opposition to stand a chance, but there might be more going on here than meets the eye.
