I know a bit about Extended already. I know the major players in the format and I keep a casual view of the metagame. So here's my current, immature analysis of the metagame:
The major players are Zoo, Faeries, Next Level Blue, Hypergenesis, and recently Dark Depths. Various Rock decks including Death Cloud also exist in some capacity. Dredge is a rogue deck that comes and goes in cycles. Everyone forgets about it, and it strikes. Everyone boards in hate, and it dies. People stop boarding in hate, and forget about it. It strikes again.
The deck I intend to begin with is Zoo. It's the only really Tier 1 aggressive deck, but comes in a few flavours. Here are the decks I considered:
- Has controllish elements in Baneslayer and Punishing Fire / Grove of the Burnwillows.
- Good lategame: something many Zoo decks lack.
- Noble Hierarch is a bad topdeck.
- Has to play 24 lands, thus has more chance of flood.
- A lot of people will be playing it, since it won PT: Austin.
- Has random tech against Hexmage Depths
- Has Jitte, which Rubin Zoo couldn't fit in.
- Sideboard seems weird.
- Spectral Procession puts a lot of strain on the manabase.
- Abuses the HELL out of landfall. I mean, seriously.
- Has very aggressive starts.
- Has better Knights than other Zoo builds.
- Can attack from less angles.
- Hasn't got much of a late-game.
- Can't really defend with it's landfall guys.
- 16 1-drops.
- Fastest Zoo deck ever.
- Runs out of gas too quickly.
- NO lategame.
- Sweeper = you lose.
Homework: Play 10 matches of Rubin Zoo (either through real-life, proxies, MODO or MWS, I'm really not picky).
