Bloodrite Invoker

The eight-mana drain ability is the entire point of this body, and it is meant to be a floor rather than a plan. The Invoker cycle was built on a single principle: print an aggressively costed early creature that also carries a mana sink no aggressive deck will ever pay for during the game it matters. A 3/1 for three mana wants to attack on turn four; the activation exists for the long, grinding games where that 3/1 has already done its job and the mana is sitting idle. That tension is the design: the cheap, fragile attacker and the expensive, repeatable life-swing live in the same card precisely so neither competes for the same turn. The drain hits any target player, which lets it close out a stalled board by chipping an opponent down or, in a pinch, stabilize your own life total against an empty hand. The fragility of the 3/1 is the cost paid for the early aggression; one point of toughness means it trades down to almost any blocker and dies to incidental damage. As a piece of color-pie work, it is black's version of a recurring drain effect stapled to a creature that does not need the ability to justify its slot, which is what keeps the activation cost honest at eight.
