Decision Setup
Snapshot generated Oct 30, 2026 3:08 AM EDT. Default marketplace fee: 10.3%. Break-open buffer is your minimum extra after-fee margin for the work and risk of opening a product: at the default $10.00 buffer, Singles Net must be at least $10.00 higher than Sealed Net before the row recommends Break open. Lower the buffer for a more aggressive opening strategy, or raise it when sealed inventory needs a larger safety margin. Release dates use MTGJSON when available; newly discovered drops without a published date keep the date they first appear in the sealed source. Fixed drop contents are established before pricing. This dated snapshot uses TCGplayer Market with Low fallback and the stored marketplace fee; it is not a strict Market-only valuation. Its Secret Lair source values can include singles below $0.25, so this view does not establish a verified $0.25 Sift comparison. Bonus and promotional cards are included only when they appear in the MTGJSON drop contents or the local Secret Lair card mapping for that row.

Decision Method
This tool compares dated generated snapshots for one named Secret Lair product per row. It retains the snapshot's stored prices and fees; changing the buffer does not refresh prices or change the product contents. Missing prices are not zero and partial singles values are not complete product valuations.
These labels are model comparisons, not recommendations. They do not predict condition, liquidity, time to sell, returns, shipping, supplies, or labor. The selected buffer is the only catch-all allowance for costs not explicitly modeled.
- Break open means Singles Net beats Sealed Net by at least the selected break-open buffer. The buffer is a fixed dollar amount applied to every row after marketplace fees.
- Sell sealed means sealed net is ahead or the known singles edge shown in Decision is too thin. Missing or unverified coverage remains Price check.
- Price check means sealed or singles pricing is incomplete enough that the row should be audited before acting.
- Priced Cards counts known-priced copies reported by the stored opened-singles snapshot; it does not certify a uniform $0.25 Sift basis across products.
