Do you want to play modern but lack the sack of gold you need to play? Well suck the life out of your opponents, with B/R Vampires.
When I designed this deck, it was about $45 cheaper
As a Midrange Deck, you are a little slow, but you have serious power in the Mid-Late game.
Deck Tech
Vampire Nighthawk: This guy screams value, he flys, he has lifelink and deathtouch, which works really well with the next card,
Stromkirk Captain: The Lord here. Giving all other Vampires +1/+1 is good, as all creatures here ARE Vampires, but handing out First Strike is brilliant, and quite effective.
Dragonskull Summit and Sulfurous Springs: The Mana Fixing here. A playset each costs about as much as a single fetch or shock land.
Duress: Hand Disruption is an important part of a Midrange Build, this hits combo decks, but if you want to throw more money into this, replacing it with Thoughtseize is a good path.
Stromkirk Noble: This guy dodges Tasigur, Snapcaster, Confidant, Swiftspear, Ascendant, Soul Sisters, the list goes on. Gets scarier as the game goes on too.
Lightning Bolt: Serves as removal for most creatures in the format, and can well be used to finish an opponent off
Terminate: Hard Removal for 2, as an added bonus, no regeneration.
Dismember: Removal for every Non-Tron creature in the format, and can effectively be cast for 1 generic, at the cost of some life.
Kalastria Highborn: Has three uses. Number 1 is suicide attacks, Number 2 is killing your creatures for emergency drain and gain. And 3 is to defend really well.
Olivia Voldaren: The deck's equivalent of a dragon, but with bonuses. A severe threat once she hits the board, so, she's a Removal Magnet.
Bloodline Keeper: This guy is a late game slaughterhouse, and is usually the part you need to push for a win. Also has a LOT of value
Gatekeeper of Malakir: A 2/2 body, with sacrifice if necessary.
Sideboard Tech:
Rakdos Charm: Beating Affinity, Splinter Twin, Tokens, and Tarmogoyf
Kolaghan's Command: If you need recursion, burn or more Affinity hate.
Witchbane Orb: Hurting Burn, 8-Rack, and Storm
Bile Blight: No Tokens for you.
Dreadbore: No Planeswalkers for you.
Self-Inflicted Wound: Killing Abzan, Naya, Goyf, Geist of Saint Traft.
