After World Championships the Odyssey Block Constructed field seems more open than ever. Walking around the tables at today's event one can see everything from Soulcatcher's Aerie to basic mountain. There's plenty of surprises in store. However, there are a number of decks that have proven their worth, and are represented in greater numbers than others. Here's an abridged run-down.
Blue-Green Madness
Mono-Black Control
When it works, it's like you've managed to sneak an extended deck into the tournament. With more mana and better spells than your opponent, Mono-Black tends to turn the unfairness up to eleven. Gary Wise ran this beast to a 6-0 at Sydney. Eight Edicts and the black Wrath handle any creatures that touch down. Mind Sludge exterminates the hand, while Diabolic Tutor, Skeletal Scrying and Tainted Pact churn through to business. Mirari, while absurdly powerful, has been deemed optional.
Punisher Blue-White
Green-White Madness
Glory also shines in this powerhouse creature feature. Tireless Tribe teams up with Wild Mongrel to ensure quick Wurms and Rootwallas. The fat doesn't stop there, however, as Phantom Centaur and Anurid Brushhopper start hitting early and rarely stop. Elephant Guide and Krosan Reclamation round out the arsenal.
Blue-Green Threshold
Dave Humpherys took this group of cards to a perfect day, earning himself a Top 8 berth. He chose to run only Mongoose and Werebear as his threshold creatures, leaving the Seton's Scouts to Raphael Levy. Careful Study and Mental Note pile high the graveyard to turn them on. Standstills compliment his one casting-cost army, as does Aether Burst. The ubiquitous Wild Mongrel, Basking Rootwalla and Wonder are here, too. Centaur Garden helps push through the final damage. The board is chocked with matchup-specific nightmares, like Squirrel Nest, Phantom Centaur and Envelop.
Blue-Green Quiet Speculation
Contrast that design with Dario Minieri's 6-0 Speculation/Madness hybrid. It boasts most of the madness package, but makes room for a pair of Speculations, along with Acorn Harvest, Deep Analysis and Krosan Reclamation in case of emergency. Otherwise, they just dig up Roars for the win.
