This is probably a default message thats displayed when you add this kind of card to your deck without a sideboard
It creates a Blood Token when itself or another Vampire enters the battlefield (once per turn) and can then sacrifice those Blood Tokens to drain your opponent of two life
If Propaganda or Ghostly Prison are too pricey, War Tax can be an interesting alternative, it's especially useful in a Rule of Law deck where you can't play multiple Sorcery speed spells, this lets you use spare mana to hassle whomever you want, it's non-targeted and scales with the game
This doesnt leave you lots to build around as a commander
Theres a solid chance that as Tarkir: Dragonstorm ages, all the Spirit Dragons will go up in price too, making it a solid future investment
