Decklists & Deck Builder

Every deck you build is saved to your personal library. You reuse a deck across as many tournaments as you like — you never rebuild the same list twice.

• My Decks — your private library, where you create, edit, duplicate, and organize your decks.
• Discover — a public gallery of decks other players chose to share, filterable by game, format, and colour or faction.

1. Open My Decks and start a new deck.
   New Deck
2. Choose the game (for example Magic: The Gathering) and the format (for example Modern or Commander).
3. Give the deck a name, then add cards with the builder.

The builder is where you assemble a deck. It searches a local card database, so results appear instantly as you type.

Adding cards

• Type a card name in the search bar and pick from the suggestions.
• Or paste a full list at once (bulk import): one card per line, with the quantity first, e.g. "4 Lightning Bolt". A "Sideboard" header or an "SB:" prefix moves the following cards to the sideboard.
• The builder flags any card name it does not recognize so you can fix it.

Games with a full builder

Four games get a first-class builder with game-specific search, stats, and zones:

• Magic: The Gathering — mana curve, colour pips, type breakdown, and an edition (printing) picker.
• Yu-Gi-Oh! — Main / Extra / Side zones, attribute and level sorting, and .ydk file import.
• Lorcana — ink icons, cost curve, and lore / strength / willpower stats.
• Riftbound — domain runes, energy curve, and the Legend / Rune / Battlefield zones.

Every other supported game uses the standard builder (search, paste import, and the text view).

View modes

Switch how the deck is displayed at any time — your choice is remembered:

• Grid — card images in a grid.
• List — compact rows with a small image.
• Table — a sortable table of stats.
• Text — a plain text list you can copy.

Editions and stats

• For Magic, open the edition picker on any card to choose a specific printing (set, collector number, art). The oldest printing is used by default.
• Stat widgets update live as you edit — mana curve, colours, and type breakdown for Magic, and the equivalent for the other full-builder games.
• A live legality check tells you whether the deck is legal for the chosen format and flags banned or restricted cards.

Working faster

Keyboard shortcuts (while a card is focused):

Each deck has a visibility setting:

• Private — only you can see it (the default).
• Public — it appears in the Discover gallery, where other players can view, like, and copy it.

For public decks you can also add hubs (tags) to group them by theme, write a primer in the notes, and see how many views and likes the deck has. When someone copies your public deck, the copy credits you as the source.

You can export any deck to a plain text file at any time.

When a tournament requires a decklist, a Submit Decklist button appears on its page after you register.

1. Pick a deck from your library, or build a new one on the spot.
2. If the deck format does not match the tournament format, a warning shows — you can still submit if the organizer allows it.
3. Submit. The tournament keeps a frozen snapshot of the deck as it was at submission time.

The same library deck can be submitted to several tournaments at once. Because each submission is a snapshot, editing your library deck later does not silently change a list you already committed to a tournament.

Locking and resubmission

• Your submission locks automatically a few minutes after the first round is generated. Once locked, you cannot change it.
• If a judge finds a problem during a deck check, they can request a resubmission — this reopens your list so you can fix and resend it.
• From the tournament, a View submission link shows your frozen list and highlights any drift from your current library deck.

When a tournament completes, the submitted lists are published as public read-only snapshots by default, linked from the standings and results. This is standard for competitive events — it lets everyone study the metagame.

The published page shows the list with card images, search, and filters. Only the organizer can turn publication off for a given event; there is no separate player opt-out.
