The MTGStocks badge, resolved by the people reading the page

MTGStocks refuses requests from cloud hosts, so this server could never build the MTGStocks link and the badge never appeared. Your browser can reach them, so opening a card now resolves that printing's page, links it, and reports it back — the next person to open the card gets the link already there. Reported links must name the card they claim to be. See full changelog for more.

🃏 Scryfall
Search cards, find by name, or get a random card. Pricing resolves down to a specific set, collector number, and finish — including whole decklists priced at the printing written on each line. Pull full oracle text for a list of cards in one call.

📚 Comprehensive Rules
The actual rulebook, on tap. Look up any rule by number or keyword — with its subrules and glossary entry — or full-text search the Comprehensive Rules. Refreshes itself when Wizards publishes a new set's rules.

🃏 Precon Decks
Search and fetch preconstructed decklists from 2700+ official decks, with Archidekt export. Diff a precon against any deck, or see how the community actually upgrades it — which cards get cut, which get added, and how often.

📈 Price Watchlist
Track card prices over time. Create a list, add cards singly or in bulk, set targets, and get a push notification when one hits your number. Lists live behind a passphrase URL at mcp.kautiontape.com/mtg/w/ with price history, a bought toggle, and cloning.

🐟 Goldfish
Simulate opening hands and turns to measure a deck's speed and consistency. Seeded Monte Carlo runs with 95% confidence intervals, paired A/B comparisons that flag whether a difference is real, exact hypergeometric draw odds, and shareable HTML reports. Measures speed and consistency only — it cannot value interaction.
