Last week, when I said I’m done… apparently I lied.
This deck will have competing parts, which just means you’ll have to mill harder.
The problem is that you’d like to use the same wincons you were using before, such as Nighthowler and Nemesis of Mortals, but milling also works with Delve creatures, such as Necropolis Fiend. Of course, you can always Delve away lands and spells, but you want have that many of them. On the other hand, there’s a limit to how big you need your Nighthowler to be…
Enablers include the mainstays from the previous deck that survive the rotation, namely Satyr Wayfinder and Commune with the Gods, but there’s also Nyx Weaver, Scout the Borders and See the Unwritten. The three mana ones aren’t as bad as you’d think at first, since if you are two-colored and your opponents are three colored, you’re probably ahead in tempo as they keep playing tapped lands. See the Unwritten is different. Its quite expensive, and its also quite random. The variance is pretty high. It also means you’ll probably need to play more lands then previously. Best case scenario is probably hitting a Necropolis Fiend, as you’ll still have stuff for its ability.
M15 clearly had an emphasis on artifacts. Khans doesn’t have much to contribute, but there’s (dare I say it) Ugin’s Nexus. Sure, everyone has noticed the interaction between that and Shrapnel Blast, but I’ll bring it up anyhow. Just put Scuttling Doom Engine in the same deck and you’re set. Well, maybe some other stuff too. Negate or two in the main can’t hurt.
Butcher of the Horde
… and we are basically butchering our own horde.
Right now, for whatever reason, Bloodstained Mire is the highest rated card in Khans on Gatherer. The second highest rated is Butcher of the Horde. I can see why. If you don’t put too much thought into it, it might seem innocuous, because you have to sacrifice cards to get anything out of it. That’s a wrong way to think about it. You should see it quite the other way around. You get to sacrifice creatures to get all sorts of extras out of a creature that is already quite powerful.
What works well with it? I’d say Crackling Doom, because I think much of the format is going to be about ramping into a huge creature early, and its good in the inevitable mirror, especially on draw. Just waste your opponents one right before playing your own (and attacking with it).
What else is good with it? Bloodsoaked Champion, which lets you sacrifice it and return it to the battlefield right after. Goblin Rabblemaster, which spits out fodder for the demon every turn. I’d also try out Mardu Ascendancy. More fodder, if nothing else.
Lifelink seems pretty important for this deck, as we are paying a lot of life for mana and other things.
