The symmetry is what marks this as a graveyard-fuel card rather than a mill wincon. When the flyer connects, everyone mills, including its controller, which is precisely the point: this is a one-mana evasive body built to feed a self-mill engine, not to grind an opponent's library toward zero. A deck that cares about cards in its own graveyard (reanimation, delirium, spells that count graveyard cards) gets a repeatable, combat-gated trigger stapled to a creature cheap enough to curve into the turns where that matters. The flying does double duty: it keeps the damage landing over a ground-clogged board, and the trigger fires only when the attack actually connects, so the mill is tied to a body you have to keep alive and swinging into an open lane. As a design it sidesteps the usual mill-tribe problem, where filling an opponent's graveyard is a liability more often than a plan, by handing the effect to an archetype that wants graveyard density regardless of whose it is. The 1/1 frame is the tax: it dies to everything and does nothing the turn it enters, so the payoff only accrues over multiple hits, and the deck has to survive long enough for a fragile evasive body to land those hits before the mill amounts to anything.
