Decks

A deck in AMTG is a list of cards you want to play together. It is separate from your collection: adding a card to a deck does not add it to the collection, and does not move it anywhere. What the deck gives you is a comparison with what you own.

(If you want to record that some cards physically sit in a deck box, that is a location of the collection, not a deck.)

Making a deck

On the Decks page, give it a name and, if you like, a format and a note. Then add cards in any of these ways:

• One at a time, on the deck's page: type the card's name (suggestions appear), the quantity, and whether it goes in the main deck or the sideboard.
• From a card's page: “Add to the deck”.
• By pasting a list, on the deck's page.

Deck lists

One card per line, as most sites and programs export them:

4 Lightning Bolt
4x Counterspell
1 Sol Ring (C21) 263
Brainstorm

Sideboard
2 Pyroblast
SB: 1 Red Elemental Blast

• The number is how many; a line with just a name is one copy.
• Set codes, collector numbers and foil marks ((C21) 263, [C21], *F*) are ignored: a deck names cards, not printings.
• Sideboard on a line by itself starts the sideboard. SB: in front of a line puts that one line there. A blank line does not start the sideboard.
• Deck, Commander and Companion go back to the main deck. A Maybeboard section is skipped.
• Titles such as Creatures (12), comments (//, #) and blank lines are ignored.

Lines that are not card names are shown to you with a suggestion and put back in the box to correct; everything else is added.

What the deck tells you

• Completion: the round gauge shows how many of the deck's cards you own, as a percentage. Any printing counts, wherever it is. 100 % means you have every copy.
• Missing: cards you do not own enough copies of for this deck.
• Contested: cards you own enough of for this deck alone, but not for all the decks that want them. If two decks each want 4 Lightning Bolt and you own 6, both decks are complete on their own and the card is contested.
• To buy the missing: an estimate, using the cheapest printing of each missing card.

The Decks page also has one list of every contested card: how many you own, how many your decks want in total, and which decks.

Statistics

Every deck has a second tab, Statistics, about its main deck:

• how many lands and how many other cards, and the average mana value of the latter;
• cards by type (an artifact creature counts as both);
• the mana curve and the colours, leaving lands out;
• the coloured mana symbols in the costs, which says how much of each colour the deck really asks for. A hybrid symbol counts for both its colours.

Other things

• “See the cards as images” searches for deck:"name"; combine it with any other filter, for example deck:dragons have:no for what you still need.
• “Download as text” gives the list back in the format above.
• A card's page shows which of your decks it is in.
• Decks are included in the JSON export and in the nightly backup.
• While the safety lock is on, decks can be looked at but not changed.
