A heavy offensive vampire deck that feeds on its own growing size.
Start off with a few low-level like the Blood Artist and Stromkirk Noble to establish some board presence. A few early attacks easily buff the Noble by +1/+1 for every time he attacks an opponent directly. And as long as you have the Artist, any creature (including it) that dies gives you life.
Those two creatures bide you time until you have enough mana to summon Stromkirk Captain, Rakish Heir, and/or Captivating Vampire. Each of these has their own effect to strengthen themselves, or buffs the vampires around them. The Kalastria Highborn is an added bonus to keep dealing damage to your opponent, utilizing its effect as lower-level vampires get destroyed or killed.
Win conditions are Bloodline Keeper and Olivia Voldaren. Strong separately, but lethal together. One buffs other vampires and keeps generating flying vampire tokens every time it is tapped, while the other has the ability to turn opponents creature into vampires and then take them over, if you have the mana to use the effect.
Other tools at hand are low-cost, but potent removal spells to decimate your opponents defenses. Urge to Feed and Feast of Blood have additional effects like buffing the vampires further, or giving you life if you start falling behind. Blade of the Bloodchief also works well when theres a lot of creatures dying and adds +2/+2 for every creature that dies while it is equipped to any vampire. Easily turning a freshly-summoned weaker vampire or vampire token an advantage.
This deck sits comfortably with 22 mana, roughly half of which is black/red. So you always have the mana you need, when you need it, early on to get ahead.
Comments and suggestions are always welcome! This is a revamp of my previous deck with the same name after a few weeks of playtime.
