Alright /edgh/, you seem to fancy yourselves quite the deckbuilders so I have a challenge for you.

This is a decklist and list of cards I found in my bulk that all vaguely center around the theme of "vampire", your challenge is to build the most functional EDH deck out of this list and explain how you're meant to win.
The rules are simple, use the cards provided within the mainboard or sideboard, if additions are needed your budget is 25$ (TCGplayer price)
Lets see how you do:

HARD MODE: no infinite combos
