Cardstock's reprint and ban risk signal is unproven — so rather than claim it works, we keep it honest in the open. Below are the cards the model is flagging right now, recorded before anything happens to them. As those cards actually get reprinted or banned, we'll show what their price did — a blind, as-of record that can just as easily prove the signal wrong.
How we keep it honest
Blind & as-of. A card's score is recorded the day it's computed, before we know whether it gets reprinted or banned. Nothing is scored with hindsight.
No leakage. Cards already spoiled in an announced set are a confirmed reprint, not a prediction — they're excluded from the flags below, which are genuine forward calls.
Recording since July 5, 2026. The resolved scorecard needs a flag from well before an event plus the price reaction after it, so the first results are expected in late 2026 and build from there.

Highest reprint risk
Cards the model thinks are most exposed to a value-dropping reprint — not yet announced.
Scored daily across the investable market — every card worth real money or heavily played, not just cards anyone owns. A research readout, not financial advice — never a “sell” call.
