First attempt at a control deck in expedition. Feedback is appreciated, though I'm not sure any further changes are needed at this point. One of the crucial changes was adding Lethrai Dead Drop. Given the large amount of removal in the deck, there will usually be few or no units on the opponent's board, meaning you can draw cards without taking damage relatively often. And even if you take 2 damage, it still seems better than using Fenris to draw cards (also costs 3, deals 3 damage to you, and you only get 1 card).
Updated the decklist again. I think this one is now about as good as I can make it. Not 100% sold on the Impending Doom, but it's definitely worth more than the Lost Scroll was. I've played well over 50 games with this list at this point, and I have not kept track strictly of the winrate, but it's over 60%.
Edit: I'm blind and can't read, there is very much a reason.
