Grim Javelineer

The trigger is the tell: it fires whenever you attack, not when this creature attacks, so the +1/+0 detaches from its own body and floats to any attacker you choose. Send anything into the red zone and you get to hand out the bump, which turns a 3/2 for into a repeatable combat lever every turn you swing, even on turns it sits back. The surveil rider is where the two halves click together: the +1/+0 exists partly to push a small creature over a blocker's toughness, and when that boosted attacker trades or dies, you dig one card deeper toward whatever your graveyard wants. It rewards the aggressive-attrition posture black has always leaned on, where creatures are meant to die and death is a resource rather than a loss. Nothing here is loud on its own: the pump is a single point, the surveil is one card, and the body folds to almost any removal. What justifies the slot is the loop: attack, buff a creature into a favorable trade, cash the death for card selection, repeat. It is a grinding engine wearing a beater's stats, meant to treat the combat step as a way to filter draws and empty the board in the same motion.
