Cephalid Inkmage
Two abilities built to feed each other. The enters-the-battlefield surveil 3 lets the caster rake as many as three cards into the graveyard per cast, and the threshold clause turns a seven-card yard into unblockable evasion. That is the loop: the fuel and the payoff on the same body, so a self-mill deck gets a beater that both stocks the graveyard and cashes it in. What keeps it from switching on turn three is arithmetic. Each cast moves at most three cards below, and surveil rewards precision rather than volume: you send only the dead cards to the yard and keep the ones you want to draw, so climbing from zero to seven takes a few turns of genuine graveyard investment. By the time the evasion comes online, you have committed to being a graveyard deck, which is exactly the deck this creature wants to be in. The Wizard framing is doing real work: surveil, unlike blind mill, lets the caster sculpt what comes next, so the same trigger that grows the yard also smooths the coming draws. It is a modest 2/2 whose ceiling is entirely conditional on the graveyard it helps build, designed to reward playing the archetype rather than to carry it alone.
