Mind Drill Assailant

The self-contained graveyard engine: a defensive body that pays into its own threshold count and then turns into a threat once the payment lands. The 2/5 base is built to hold a ground stall while the surveil ability, repeatable at instant speed for three mana each activation, digs toward seven cards in the graveyard. Cross that line and the +3/+0 turns a wall into a genuine 5/5 clock, so the same card that stabilizes the early turns closes them out later. What makes the design work is that surveil does double duty: it fills the graveyard to switch threshold on while also smoothing draws, and the mana flexibility on both the cost and the activation () lets the card slot into a dedicated black-blue graveyard shell or splash into either color alone. Threshold is an old mechanic being asked to do modern work here, paired with a self-mill outlet on the same creature rather than relying on external enablers. The tension is speed against payoff: seven cards is a real investment, and every activation trades tempo and mana for progress toward a body that only matters if the game goes long. It is a card built for the grind, not the race.
