Scarblade Scout
On a bare 2/2, lifelink and self-mill pull in opposite directions: lifelink wants you racing and attacking, self-mill wants your graveyard stocked for something else. That tension is the design. This is a creature built to service a deck that treats its graveyard as a resource, not a dumping ground: reanimation targets, delve fuel, threshold counts, escape costs, an aristocrats loop that recurs whatever hits the yard. The body earns its keep by being a real attacker while it does the digging, and the lifelink buys back a sliver of the tempo you spend churning through your library. Green has usually filled graveyards by dredging or self-milling in bulk; black's version has more often asked you to sacrifice or discard to get there. Here the mill is stapled to a creature that also blocks, attacks, and gains life, so the fuel arrives as a side effect of a body you were happy to cast anyway. That is the quiet efficiency of the design: it never asks you to spend a card on the enabler, because the enabler is also a two-drop you can hold up in the red zone.
