Cheap flavorful tribal vampire deck, "convince" your enemies to work for you and then brutally murder them for more power.
The idea is to use Mark of Mutiny or Act of Treason on the first phase to convert a defender, swing with them (possibly after adding a +1/+1) and your vampires (which gain +1/+1 counters from hitting the other player) in the combat phase, and then sacrifice the converted creature with Bloodflow Connoisseur or Bone Splinters to gain even more +1/+1 counters or score another kill.
Any time you sacrifice, or just plain kill something, Havengul Vampire also gains a counter and Blade of the Bloodchief will generate two counters.
Another interesting combo here is using Thatcher Revolt to generate three hasted 1/1 tokens on the first phase, swing with them in combat (who are likely to get past blockers since the vampires are more important to stall), then sacrifice all of them in the 2nd phase. Even if you lack Bloodflow Connoisseur they are sacrificed so Havengul Vampire and Blade of the Bloodchief will benefit anyway.
Deck was around ten dollars when I bought it, Stromkirk Noble is a bit over 50 cents each, Drana, Kalastria Bloodchief and Blade of the Bloodchief are about 1.00-1.50 (edit: much more now.) but Drana at least is optional, I felt I had to have her due to her artwork and the fact that every deck should have at least one legendary because reasons.
If you have enough dosh to spare you can upgrade your 4x Bloodflow Connoisseur to 4x Falkenrath Aristocrat, you will gain flying, haste, +3/0 and switch your sacrifice benefit to indestructible (or both that and +1/+1 if you sacrifice an enemy's converted human or Thatcher Revolt token) for only one more mana cost.
Blade of the Bloodchief is also really, really good so if you have money consider getting more of those.
Should be noted that nearly every card in this deck uses +1/+1s, so if you find red/black cards that can exploit that, consider using them.
Suggestions are welcome but this deck is pretty tight, so not sure if I could work anything else into it.
