Blighted Blackthorn

Here is a card-advantage engine built on a self-directed knife: blight always points at your own board. The tall 3/7 frame reads like a wall, but the value is gated behind swinging, not stalling: the pull fires when it enters and again when it attacks, so drawing cards means committing this body to combat turn after turn. Each activation costs a life and drops two -1/-1 counters onto a creature you control, shrinking that creature by two in both power and toughness. That makes blight a resource loop with two exits: it either grinds a chosen creature toward death, feeding whatever cares about counters or dying bodies, or it eats into the Blackthorn's own generous stats, so a 3/7 becomes a 1/5 becomes something that can no longer connect. The design inverts the usual black draw tax. Where cards in the Necropotence lineage pay life for cards, this pays life and board state, but it hands you the board state to spend: you choose which creature absorbs the counters, so the drawback becomes a delivery mechanism. Point it at fragile utility creatures you wanted dead anyway and the counters stop reading as a cost. The high toughness matters precisely because the engine demands attacking: it survives the swing-back that a fragile five-drop would not, buying the repeated triggers. The whole card is an argument that a downside placed on your own permanents is only a downside until you build to want it.
