Only 4 Goblins in a field of 193? You must be joking (right?). I'm expecting there to be a lot more Goblin decks in the meta after 2 made the top 4 at this event. Them's Survival numbers! I also expect High Tide/Time Spiral/Emrakul to see some play, as it's relatively cheap to build and got a lot of coverage this tourny.
I definitely feel a sense of validation seeing Goblins do so well in the first large post-Survival event. I feel like I've been backing the right horse, that the characteristics that drew me to the deck in the first place are valid and viable. The only downside to this event: Where do we go from here? How do we plot against a metagame where we're the top-dog?
That brings up a point I'd like to make about Legacy in general. There was a Pro in the SCG booth between rounds (Mike Jacob) and he was doing some commentary that basicly consisted of bashing the Legacy format and talking about how terrible every deck was. He lamented how it was impossible to play a deck without Force of Will that didn't suck, that losing T2 isn't good for the format, and that most of the cards people play are bad cards. He was generally obnoxious, but his comments revealed his thinking about Magic formats and how they should be played. To him, the most important part of Magic is the metagame, and breaking the metagame to put up a big Pro win is the ultimate goal. His reasoning for Legacy being a bad format then is that it's a format where the meta cannot be broken.
I know, I know. A lot of you are thinking "What about Survival?" but SurvivalVines was an Archetype that showed up in Columbus and slowly grew in strength and popularity. Over the next 5 months it took over and dominated the format and was then banned. Survival was an excellent deck, but it didn't become that way by expliting holes in the metagame. It was just the best deck, period.
Here's the big 'contrast and compare' part of the show. Mike Jacob was basically saying that Legacy is a bad format because you can't break the metagame. You can't show up to a tournament with a new piece of tech or build that will give you a noticable edge against Deck X, but won't lose any leverage against Deck Y. To Mike, this is the essence of Magic: building and tuning a deck to take on the metagame. In Legacy, on the other hand, it's all about building a deck that can control the game as quickly as possible, usually just by winning it. The metagame is almost moot in Legacy. You're generally trying to put as much power on the table as quickly as possible. You're not asking youself if you can beat X, Y, and Z. The question is, can you beat Anything?
So that's my take Legacy v Standard/Extended.
