The two-card mill reads as incidental, but it is the entire reason a 2/1 for two exists at this rate. A body like that has never been scarce; the payment is that the self-mill happens once, on entry, with no setup and no second mana investment, feeding a graveyard the way a draw step never could. That fixes the card in the support tier of a delve-and-reanimation shell: it stocks the yard for delve costs, throws fuel under spells that count graveyard size, and occasionally buries a target worth bringing back. The friction is that the mill hits your own library, not an opponent's, so it only earns its keep when those two cards become an asset rather than a cost; strip away the graveyard payoff and it is a worse two-drop than a plain beater. That conditional value is the design point. The 2/1 body means a missing synergy does not leave you with a dead draw, while the enter trigger rewards a build that treats the graveyard as a resource. This is the cheap-self-mill creature pattern in miniature: power gated behind a deck commitment rather than stamped on the card outright, with the cost of admission paid in deckbuilding, not in mana.
