I know I'm going to get flamed for this, (even though its honestly never happened to me here.) but let's take a look at this. SJC Atlanta is this weekend, and what ever wins will be copied by medium level players all over the country. Its a sad sad situation, but only the top tier players of the country are creative and innovative. If you want to understand what I mean read my thread I'm starting after I post this. Now here's my opinion on some decks.
OTK Decks:
They suffer from being horribly unreliable and therefore won't see teir one play. By OTK I mean, Cyber OTK, Ben Kei,
Last Turn, and
Rescue Cat (Yes I threw
Rescue Cat decks in there, what I'm crazy)
Warriors:
Honestly, they have a tendency to over extend themselves, and then you're finished by a good
Dark Hole or Vortex. They need to play more conservativly to be tier 1.
Zombie's:
The most dangerous deck type today. Thanks to DDV and a few other things seeing as it was already tier 1, and its super strong.
Gravekeeper's:
They have one major weakness. Its also its greatest strength.
Necrovalley. On the whole its slow to get that card, but once you have it, its game on and game over for the opponent.
Fiends:
Umm, Yeah I think enough has been said here.
Tomato Control:
I haven't heard anyone say anything about this deck type, but its very dangerous. One of my teammates played it this weekend, and beat out 3 Gravekeeper decks back to back. It was amazing. Its definitly something to keep in mind, and be feared.
All said and done we'll see the new Tier 1 after this Sat.
