Really bitchy black enchantments that limit everything that your opponent can do.
Use Augur of Skulls and
Black Cat
as chump blockers for the creatures that you have enchanted with
Stab Wound
or Sinister Possession. You will be able to keep at least one creature on the field pretty much all the time, and since they are only 1/1 you wont be destroying the enchanted creature.
Oona's Prowler is sick because, similar to Painful Quandary, you can choose between taking damage or discarding a card. I used to have
Basilica Screecher
s, but I like this card better.
If you are worried about a creature/planeswalker that will really mess you up, side in Hero's Downfall. If against big early game creatures,
Vampiric Link
works out nicely. Most of the time your opponent will not get the chance to drop any late game creatures or spells, so you're really just worried about the goyf.
Sinister Possession is godly against aggressive one drops, or even defenders. It also pisses people off who want to swing their Stab Wound-ed creature in hopes that I will block and kill it.
Just about every turn you will be hitting your opponent for non-combat damage that really adds up over time, especially once you start throwing more
Stab Wound
s and Shrieking Afflictions out. Some well placed discards can make it to where your opponent will surely take the damage from Shrieking Affliction and Bloodchief Ascension.
Underworld Dreams for decks that keep drawing cards.
