Digimon TCG Deck Builder
Most deck builders let you assemble 50 cards you may not own. DigiFoundry's builder is wired to your real collection: as you add a card it tells you how many copies you own, how many are already committed to another deck, and how many are genuinely free to use.
Free account · your collection stays private by default · export any deck as plain text
It builds from copies, not card names
Every card in the builder is checked against the physical copies you have recorded. If you own four copies of a card and two are already sitting in another deck, the builder says so before you plan around them.
Example: one card, four copies
- Owned
- 4
- In decks
- 2
- Trade list
- 1
- Available
- 2
The numbers deliberately do not sum. Only owned decks reserve copies, so Available = Owned − copies in owned decks. The trade list is a label: one of those two available copies is also up for trade, and marking it never takes it out of circulation.
Import a list
Paste a deck list as text and DigiFoundry matches the card numbers. Anything it cannot match is reported back rather than silently dropped.
Export a list
Copy any deck out as plain text, or in the format DCGO expects, to share it or take it elsewhere.
Count proxies separately
Mark how many copies in a slot are proxies. They stay in the deck list and its counts, but never reserve a real copy or show up as something you are missing.
Fill the gaps
Send every missing card straight to your want list, so the next time you are buying you know exactly what the deck still needs.
A real deck, checked against a collection
This is VB, a 50-card deck published by Exodus_AU. Open any card to see what it does, or run the whole list against your collection in one click.
Deck builder questions
Do I need to own the cards to build a deck?
No. You can build any deck you like — the collection check is information, not a restriction. It tells you what you would need to buy or borrow to sleeve the deck up for real.
Does putting a card in a deck remove it from my trade list?
No. The trade list is a label, not a location. A copy can sit in a deck and still be listed as tradeable — only owned decks reduce how many copies are available.
Do alternate arts count as the same card?
Yes. Parallels and alternate arts of a card share its base card number, so any printing fills the slot — in the builder, in the collection check and on the card database.
Can I bring a deck in from somewhere else?
Paste the list as text and the builder matches it by card number, reporting anything it could not find. You can export the same way once you are done.
Is my collection public?
Not unless you choose to share it. Decks are private until you publish them, and collection sharing is opt-in per friend. See the privacy policy for detail.
What does it cost?
Nothing. Create a free account, record what you own, and build as many decks as you want.
