First off, thanks to Mallumo for an awesome decklist and write-up! I really like this version, especially the Nagash/Promenade combo. I might opt for Vanguards of Woe over Vile Sorcs for their "go ahead and remove me" effect while Quest-sitting. I'd also be tempted to sneak in slave Pens for a little more mileage from Raiding Ships and general silliness potential. Caught the Scent is the only cut I'm seeing, or maybe the third Makurth. I'm kind of tempted by Hellbane's Raiders, too, but still very much on the fence.
In general, it seems like there are a lot of ways to go with DE discard right now. Sorceress Convent/Raiding Ships instantly made hand discard viable, but I'm seeing at least three other broad archetypes, and lots of options within those:
-Turbo Quest with 3x Ancient Map to get multiple Ships in play early, plus 9-12 DE supports and Walking Sac/Vanguards. The targeted discard/Promenade doesn't work here, but you have a better shot at keeping their hand empty on your turn.
-Deck/Hand Hybrid Discard w/ Promenade. Discarding from their deck can let you see more cards, and doesn't require them to have cards in hand for you to hit stuff with Promenade.
-Mostly-deck discard with a little hand discard. Here you now have three options:
=Old-school Plague Monk w/ max spells.
=Bannermen of the Crag - Probably w/ necro/free units and Sacrificial Pyre. Like Plague Monk, needs to hit two of its guy a lot of the time.
=Hodge-Podge with some combo of Monk, Bannerman, and utility stuff like Bathe in the Cauldron, multiple Barbed Snares, possibly Infiltrate!.
Barbed Snares can be a really nasty finisher, especailly with Whip the Slaves in the deck. Being able to play them in Kingdom and immediately draw them back up again (and again with Lash) means you can get a pretty big chunk in one fell swoop.
I also think the presense of off-turn discard stuff like Bathe in the Cauldrn and Gaze of Nagash makes it easier for discard decks to play combat tricks like Invoke Kaine's Wrath and Take Captive, which haven't really made the cut in the past. Not sure which versions of discard could make the best use of them, but in theory extending the game with stall tactics is a very good thing for discard strategies.
Anybody else have lists?
