Arkham, the 1920's. Investigators battle horrors from beyond time and space, risking life and sanity while conspiracies of cultists and malign servitors seek gateways for their outer gods to return...
Soon, the stars will be right! Great Cthulhu shall rise!
I am pleased to see a Jund deck and DotP embracing multi color now they have sorted out man tapping. Not many new cards among these list, hopefully some of the other decks will focus on the upcoming core set. The Sliver one should be good.
A nice assortment of deck from different planes. We already knew Innistrad is one of the locations visited in the campaign mode, now we know that we'll also be seeing Ravnica (duh), Alara, and Zendikar.
Chant of the Mul Daya isn't quite as awesome as Ancient Depths was (no Lorthos) but it's still pretty sweet to have a deck full of Eldrazi in DotP.
It's a little weird how the Dimir deck doesn't actually get any Cipher cards until the last third of its unlocks. I'd have expected there to be at least a handful in the basic decklist.
