Fraying Sanity

Most mill cards mill a fixed number and ask you to stack enough of them to outrace the opponent's draw step. This one inverts that math: it pays back every card that reaches the enchanted player's graveyard, from any source, across the whole turn. Cast a Glimpse the Unthinkable for ten, and the end step doubles it. Force a discard, kill a creature, sacrifice their permanents, let them crack a fetch: each event feeds the counter, and the Curse cashes the entire turn's tally a second time. Left alone on an empty board it ticks zero, so it is not a clock on its own; it is a multiplier bolted onto whatever else you were already doing to fill their yard. That makes it a poor standalone threat and a far stronger engine piece than the rate suggests, because it scales with disruption rather than competing against it. The "from anywhere this turn" clause is the load-bearing phrase: it catches surveil, self-mill, their own fetch cracks, any graveyard event regardless of who caused it, meaning a careless opponent can accelerate their own demise. The Curse subtype does not turn it into a win condition by itself; it still demands a dedicated shell built to keep cards flowing into a graveyard. What it does well is stop asking the rest of that shell to be a clock too. Everything the deck was already doing to grind now mills twice.
