Secret Lair Break/Sell Radar

This ProTool models the Secret Lair break-or-sell question: break open only when opened singles clear your buffer after fees, otherwise sell sealed or flag the row for a manual price check.

Decision Setup

Snapshot generated Jul 8, 2026 5:07 PM 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. Drop contents are loaded first, then pricing coverage and Sifted Cards are reported from the opened-singles snapshot. 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.

Secret Lair sealed versus opened-singles break or sell decisions

Decision Method

This is the ProTools version of the Secret Lair page we discussed earlier: instead of asking the browser to fetch each drop one by one, it reads a daily snapshot and ranks every drop by the same break-open logic added to the public calculator.
