Deck Builder

The deck builder lets you create and manage competitive TCG decks alongside your collection. It supports all 6 TCGs — Pokémon, MTG, Yu-Gi-Oh!, Lorcana, One Piece, and Riftbound — and cross-references deck lists against your portfolios so you can see what you own and what you still need to buy.

Creating a Deck

1. Navigate to Decks (top bar on desktop, More menu on mobile)
2. Select a TCG from the game filter pills
3. Click New Deck and give it a name
4. Search for cards and add them with one click
5. Adjust quantities with the +/− controls

Ownership Tracking

Each card in a deck shows one of three states:

• Need — you don't own this card in any portfolio
• Owned — you own it but haven't marked it
• ✓ Owned — confirmed owned

Ownership is cross-referenced against all portfolios and only counts raw cards (not graded slabs — you wouldn't sleeve a PSA 10 into a deck).

Cost Calculation

The deck builder calculates the total cost to complete the deck — the sum of market prices for all cards you still Need. This gives you a quick answer to "how much would it cost me to build this deck right now?"

Completion Percentage

A progress bar shows how close you are to having every card in the deck, based on ownership status.

Meta Decks

Rarebox fetches current tournament meta data from Limitless TCG and shows the top competitive decks ranked by meta share and championship points. Meta decks are available for all 6 TCGs.

How Meta Decks Work

1. The metaDecksApi service fetches live data from the serverless endpoint (/api/search)
2. Core cards are resolved server-side with exact card match (set code + number)
3. Market prices for every card are fetched from the appropriate TCG API
4. Results are cached in localStorage for 24 hours — instant on repeat visits
5. If the live endpoint is unavailable, static fallback decks are shown

Importing a Meta Deck

Click any meta deck to see its full card list. Click Import to copy it into your deck builder as a new deck. You can then customize it and track ownership against your collection.

Multi-TCG Deck Support

Each deck has a game field that determines which TCG's cards it contains. The deck builder uses multiSearch to find cards across all providers, so you can search for MTG cards in an MTG deck, Yu-Gi-Oh! cards in a Yu-Gi-Oh! deck, and so on.

Card images and prices are resolved from the appropriate API for the deck's game.
