Search cards by name/colors/rarity/set/type. colors is WUBRG letters; set_code is the 3-letter set. Set owned_only=true to restrict to cards the player owns.

List cards the player owns (owned count >= 1), with the same optional filters as search_cards.

Cards in a set the player hasn't completed a playset (4) of. Returns a 'needed' count per card. Optional rarity filter.

Collection overview: distinct owned, total copies, per-rarity breakdown, and wildcard/currency balances.

Run an ad-hoc read-only SELECT against the collection database. Tables: cards, collection(grp_id,count), wildcards(kind,count). Join collection on cards.grp_id for owned counts.

Import a decklist and store it for buildability analysis. Provide exactly one of text (pasted Arena/MTGO list) or url (Archidekt or Moxfield). Optional meta metadata: best_of (1 or 3), tier, meta_share (0..1) feed the best_buildable_deck ranking. Set allow_scrape=true to attempt an MTGGoldfish URL (unreliable). Returns the deck id and any card names that couldn't be matched.

List stored decks with format, best_of, tier and source.

Cards and wildcards needed to complete a deck (by id or name), given your collection. Basics are excluded; copies are capped at a playset (4).

Across all stored decks (optionally one format), rank cards to craft by how many decks they would unlock, then by how many decks need them.

The best deck you could build given your cards and the meta. Ranks stored decks by meta strength x buildability. Filter by best_of (1 or 3) and format; max_wildcards hides decks needing more than that many wildcards.

Delete a stored deck by id or name.
