[draft]Pharika, God of Affliction[/draft]
Self-mill is key here, so some Dredge.
Pharika’s Two-Colored Cards
I like the flavor of black-green, so there’s plenty of cards I’d like to use here.
[card]Catacomb Sifter[/card] is a very efficient creature. The scrying ability is very strong, especially with what I want to do with this deck.
[card]Deadbridge Chant[/card] gives continuous card advantage in a fun way. Also, if you get one of the delve cards I put into the cube (with Phenax), this can be very strong.
[card]Drown in Filth[/card] is both self-mill and fair removal. It can miss badly, but at least it mills.
[card]Gift of the Deity[/card] has an interesting effect in this deck, since its going to have plenty of deathtouch.
[card]Grave-Shell Scarab[/card] provides Dredge.
[card]Lotleth Troll[/card] is an interesting card that’s very hard to evaluate. Its pretty bad card disadvantage, but at the same time, getting those creatures into your graveyard can be good as well.
[card]Necrogenesis[/card] is an alternative payoff for self-mill if you can’t find Pharika.
[card]Nyx Weaver[/card] is good self-mill, but also can get you something from the graveyard.
[card]Pharika’s Mender[/card] is flavorful.
[card]Rot Farm Skeleton[/card] is continuous self-mill.
[card]Spiderspawning[/card] is very strong. Maybe too strong.
[card]Varolz, the Scar-Striped[/card] could be another payoff card.
This is kind of hard, actually, but I guess this:
Gift of the Deity
Rot Farm Skeleton[/draft]
First, Deathtouch enables easy trading with quite a few creatures. You get benefit from those creatures anyhow.
[card]Typhoid Rats[/card] and [card]Pharika’s Chosen[/card] are easy choices. So is [card]Graveblade Marauder[/card], although it can be quite oppressive at times. [card]Ukud Cobra[/card] is somewhat unassuming, but very powerful. Lastly, one of the best creatures around: [card]Vampire Nighthawk[/card].
[card]Harvester of Souls[/card] is in the Deathtouch camp, but also gives you other benefits, so its in.
Also, a couple of Dredge cards: [card]Necroplasm[/card] can be very poor in this deck at times, but its an interesting card. [card]Stinkweed Imp[/card] doesn’t quite have Deathtouch, but almost, so its actually in two camps here.
Harvester of Souls
Here we want pretty much the same thing as above, so first cheap Deathtouchers like [card]Ambush Viper[/card], [card]Deadly Recluse[/card], [card]Heir of the Wilds[/card], [card]Nightshade Peddler[/card] and [card]Sedge Scorpion[/card]. Also [card]Acidic Slime[/card].
Green does have something more though. It can force confrontations through Fights. The best way to do this [card]Setessan Tactics[/card].
I also want [card]Nemesis of Mortals[/card] in the cube, because of how nicely it works with self-mill.
This leaves room for one Dredge-card: [card]Golgari Grave-Troll[/card] (assuming I can find one cheap enough).
Heir of the Wilds
Nemesis of Mortals
