Ashcoat of the Shadow Swarm
Two abilities, two different jobs, both engineered around the same premise: your board is wide and your graveyard is deep. The attack-or-block trigger is a quadratic anthem, scaling every other Rat by the total Rat count, so a modest swarm turns lethal the moment this creature commits to combat; the bonus grows with the board rather than sitting at a fixed number, which is exactly the reward a go-wide tribal deck wants for building out its ranks. The end-step clause is the refuel valve that keeps that board from running dry: a self-mill of four that hands back up to two Rat creatures from the yard, converting library depth into recurring bodies. That pairing is the design point. The pump wants you flooding the board and spending it aggressively; the recursion makes that spend cheap, since fallen Rats are not gone so much as briefly filed. The 3/4 body is fair enough for its cost, but the card is not priced as a beater. It is priced as the engine at the center of a Rat deck, the piece that turns a pile of small vermin into both a clock and a grind. The self-mill carries the usual risk of dropping a card you would rather have drawn into the graveyard, but for a tribe that wants its creatures there anyway, that friction reads more as fuel than cost.
