It's an excellent trapping for Arcane Background: Black Magic. You know, the standard AB for evildoers.
Side note: AB (Blessed) is literally a gift from the good gods. If you're not Good then they will cut you off. There's a reason that manitous cannot use Blessed powers, even when they're in control of the harrowed blessed. Changing that makes your Deadlands a lot more corruptible than the (highly corruptible) base setting.
