Gorging Vulture

The trick here is that self-mill and lifegain usually pull in opposite directions: one wants a stocked graveyard, the other wants a stabilized board, and most cards asking you to fill a bin do so at the cost of your own resources. This one splits the difference by making the payoff conditional on what actually falls off the top. Mill four is deterministic; the life you get back is not, scaling with the density of creatures in your deck. Build a creature-light control shell and it mills you toward whatever your graveyard cares about while gaining nothing. Build a creature-heavy midrange deck and the same trigger stitches a few points of life onto an evasive body that trades or blocks fliers. The flying 2/2 is deliberately unremarkable so the enters-the-battlefield line carries the card, and the four-card yard filling is the half worth building around: it feeds recursion, delirium, threshold, escape, and reanimation targets in one motion, with the lifegain as a hedge against the mill hurting a deck that also wants a tall library. It is a modest, well-shaped piece of graveyard support, priced so that the value engine attached to it never overshadows the small evasive attacker you are actually paying for.
