Secret Lair Break/Sell Radar

This ProTool turns the Secret Lair sealed-vs-singles calculator into a decision table: break open only when opened singles clear your buffer after fees, otherwise sell sealed or flag the row for a manual price check.

ProTools access unlocks every tool row

All rows remain sortable and filterable in preview mode, with a 10% readable sample visible. The rest is blurred until you log in with the ProTool Tier or higher on Patreon.

Decision Setup

Snapshot generated May 24, 2026 1:32 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.

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.
