The cheapest card
is the one you already own.

Everyone else makes you bring a target deck and grades you against it. Chaos Cache takes the cards already in your house, tells you what they can already build, and tells you which box each one is sleeping in.

Why it's different

everyone else"Here's a deck. It costs $412 to buy."
Chaos Cache"You own 94 of the 100. That's $412 already on your shelf, and $23 to finish."
everyone else"Budget alternative: a $2 card." (It quietly kills your combo.)
Chaos Cache"Careful: that card is a combo piece with what's in this deck. A substitute won't keep it."
everyone elseType in every card by hand.

What it does

Scanning is filing

Feed it a folder of card scans. It reads each card and matches it against about 110,000 printings. Sure matches file themselves, and unsure ones wait for a one-keystroke check.

It knows which box

The folder you scanned into becomes where the card lives. "You own it, and it's in Box 2." Search, sort, and total up a box's value.

Deck check

Paste any decklist. For every card: how many you own, which box each copy is in, and what the missing ones cost, plus cards you already own that could fill the gap.

Combos with what you own

Browse every combo for free. With the unlock, see the ones your boxes can already assemble, the ones you're a single card away from, and which one purchase unlocks the most.

Bring your collection

Already catalogued somewhere else? Import the CSV. Got a deck in sleeves? Paste the list as cards you own, so nothing gets typed twice.

Bring the AI you work with

No chatbot subscription bolted on. An MCP socket lets the AI you already work with ask your collection questions directly.

What it costs

Free to use: scanning, your collection, imports, backups, deck checks, the phone app, and browsing every combo.

A one-time unlock for three extras: combos with what you own, the deck builder, and the deck editor. No subscription, ever.
