Secret Pack crafting, explained.
A quick guide to using the planner and avoiding repeated pack unlocks.
How do free Secret Pack pulls work?
When you craft an eligible SR or UR card associated with a Secret Pack, Master Duel may unlock the pack and offer a free pull the first time that pack qualifies for the reward. Packcraft helps you plan those potential one-time rewards. Always verify the offer in the game before spending crafting points.
Why does one SR card show several packs?
Some cards are available in more than one Secret Pack. If an SR craft is associated with four packs, it may help unlock four different packs. The number shown on Packcraft decreases as you mark those packs as claimed.
Can a pack count twice when different cards unlock it?
No. Every Secret Pack is represented by one shared checklist item. Marking it claimed removes it from the potential gains of every card linked to that pack.
Why does the list say 246 packs instead of 247?
The source spreadsheet contains 247 spreadsheet rows including its header. That leaves 246 distinct Secret Pack entries. The initial version of Packcraft maps those 246 packs to 157 suggested cards.
What does the “Best next craft” recommendation mean?
It's the available card associated with the most packs that you haven't marked as claimed. The route below it updates after accounting for the packs covered by earlier choices. It is a planning aid, not a guarantee that the game will award each pull.
Do I need an account?
No. Packcraft does not connect to your game account and has no website sign-in. You manually mark the packs you've claimed.
Will my progress still be here tomorrow?
Normally, yes. The checklist is saved using this browser's local storage for this website's domain. Clearing browser data, using private mode, or changing devices or domains can remove or separate that progress.
How can I move my checklist to another device?
Choose Export backup on the tracker, transfer the downloaded JSON file to the other device, then choose Import backup. This transfers the checklist without creating an account.
Why do I need to check “How to Obtain” in Master Duel?
The catalog comes from a community-maintained spreadsheet and may not reflect newly released, removed, or changed packs. The in-game information is the final reference before using SR crafting points.
Is this an official Konami website?
No. Packcraft Master Duel is an independent fan project and is not affiliated with or endorsed by Konami.
