Link to Part 2
Here are the Drana decks. Four are from Wizards, and one is from the SCG competition. Drana did not do so well competitively, I guess. The BFZ mana base allows for a lot of splashing.
Here are two Atarka decks, one from Wizards, the other from the SCG competition.
Here are two other SCG competitive decks, the lone Red Deck Wins (RDW) deck, and an Ulamog deck.
Here are the remaining decks from Wizards.
Deck 3 uses Zada, Hedron Grinder, and deck 4 is a Ulamog deck.
Deck 12 uses two retreats; deck 13 showcases Bant (White/Blue/Green) planeswalkers.
Deck 14 has a bunch of Eldrazi (awesome!) and deck 20 is an Abzan deck.
