Cephalid Vandal

The escalation is arithmetic but the damage is quadratic: the shred counter ticks up by one each of your upkeeps, so you mill one, then two, then three, then four, and the running total piles up faster than the per-turn number suggests. It is an early honest version of self-mill as an engine rather than an accident, a clock you set against your own library and then race to cash in before it empties. The 1/1 body is incidental; it exists to carry the counters and survive a turn or two while they grow. What makes the card a build-around is that the entire payoff lives off the card. Left alone it is just a slow, accelerating way to deck yourself, which is why it belongs in shells where a fat graveyard is fuel instead of a loss: reanimation, recursion, threshold and other graveyard-count triggers that want the yard stocked in a hurry. And it poses the problem every self-mill enabler since has had to answer: a counter that only grows is a resource you cannot throttle, so the deck has to be ready to convert the graveyard the moment it is large rather than wait for a clean turn. There is no flashback safety valve here, no instant-speed escape hatch, no way to slow the dig once it starts: just a creature that keeps shoveling your library into your graveyard at a rising rate until something finally turns the pile into a win.
