Ehhhhhh maybe it needs a revision... What do you suggest? It's ok if I remove a bloodline keeper and I put a swamp instead? Is it enough?
Depends on how you want to run the deck. Do you want max vampires or be able to control the board?
I have a similar deck where I use vampire rogues and cards like
feast of blood,
urge to feed,
murder and
hex.
For creatures I love the
crypt ghast for ramping and his extort is just a added bonus. Just about all the creature eliminating cards I use in this deck were put in purposely to be able to use against black cards (especially vampires)
