Mill as a side effect of combat, on a body too small to land that combat reliably: this is the design problem baked into the card. The trigger only fires when a 1/1 connects with a player, which means a Wizard with no evasion and no protection has to find a way past every blocker first, and even then the payout is one card, chosen from two revealed off the top. That is a slow clock and a soft one. The card belongs to the small school of early-Odyssey self-mill and graveyard-feeding effects, where filling a yard was its own reward and threshold turned dead cards into a resource, but it points its mill at the opponent rather than the controller, which puts it in an awkward middle: too gentle to be a real mill plan, too dependent on combat to be reliable disruption. What makes it more than a footnote is the choice clause. You do not bin a random card; you see two and pick, which lets you strip a known answer or deny a graveyard payoff your opponent wants back. The effect is sharper than the rate, and the body is the tax you pay for it.
