A lot of exciting MH2 cards (more cascade and suspend); we'll see if it works!
I'm minimizing the doubles again; I still think 1 in each color is... OK. I'd still like to find replacements for the doubled single-color lands (Barren Moore, etc.).
Especially with the new priest, WB just makes more sense as reanimator. To some degree this means black is just the "graveyard recursion" color (BU Mill, BG Spawning, BR Cast), but maybe that's OK.
Adding more mill to blue; they're not designed as engines, but more as gotcha's against the greedy control decks that otherwise have the board locked. Peregrine Drake (alongside Cloud of Faeries) should hopefully make Escape Protocol a lot more interesting.
