This is my mana-ramp extort deck, that allows me to play some expensive combos, as well as suck the life from my opponents.
Creature Core
Useful late-game. He allows me to have flying chum-blockers. I usually just sacrifice a harpy on each upkeep unless I have Tenacious Dead on the field, where I can just pay 2 mana and not sacrifice anything.
This provides some early drops as a two drop deathtouch, and can help my
Gray Merchant of Asphodel
s be more useful after they enter the battlefield.
2 drop flyer with extort. Just a great low-drop card to use in this deck.
Mono-black control that makes the opponent sack creatures? Absolutely. Oh, and it's a 6/6 for 4 mana? Splendid!
Erebos is great against anyone playing lifegain, and it also allows the drawing of cards. Since this deck also has lifegain, it should be less of a problem.
Combo this with Tenacious Dead and you have an expensive extort. I use this combo as a last resort if I keep drawing mana with nothing else to play.
This guy is the bomb of the deck, because all of that black devotion comes into play.
This makes the combo with Tenacious Dead and
Gnawing Zombie
a lot more worthwhile because it'll give me a 1/1 Rat with Deathtouch in addition to the extort. This also is great with any of the opponent's creatures dying.
I can combo this with
Gnawing Zombie
, and he's a generally awesome 1-drop. He doesn't regenerate like
Dutiful Thrull
but he allows me to combo if he blocks.
Spells (Instants and Sorceries
Naturally, I put this in because I have mono-black and mana-ramp. Allows me to get my big guys out.
Every mono-black deck should have a doom blade, but I have
Dark Betrayal
s in my sideboard if I happen to be facing an opponent playing black.
This is just a great destruction card.
Instant 2-drop damage and gain life. Love it.
Enchantments
Useful with Liliana of the Dark Realms because of all them swamps. Can also kill Indestructibles
Artifacts
This helps with the lifegain so I can use Erebos's abilities more efficiently. And of course, bringing back dead
Gray Merchant of Asphodel
s.
Land
Provides all the mana-ramp I need to get some of those nice high-drops.
Planeswalkers
Liliana is here so I can get tons of mana. I rarely use her -3 ability, but it is very useful if my opponent should use an indestructible creature.
