MTG Standard Deck Stats Tracker

(Formerly Pickpocket Match Log. The Notion databases keep their original names.)

Bo3 match tracker for MTG decks under test. Next.js 14 on Vercel, with decks and matches stored in two Notion databases (same pattern as hathcocked-recipes).

• Decks (Pickpocket Decks): name, format, archetype, colors, the Arena-format main deck and sideboard, a sideboard guide, and a testing gate. Add one from Add a deck in the app, or as a row in Notion.
• Matches (Pickpocket Match Log): each match links to a deck. The opponent is a current meta deck, or Not in meta with a basic type (Aggro, Midrange, Control, Combo, Ramp, Tempo), colors and an optional name.
• The meta list is the options of the match log's Opponent select in Notion. Add, rename or reorder options there; the first five always show in the opponent table. Keep Not in meta as an option.
• Start page (/): pick a deck or add a new one. Each deck has its own page at /decks/<id>; old /?deck=<id> links redirect there.
• Pre-test report: on every deck page, computed from the decklist plus Scryfall card data (lib/pretest.mjs, cached for a week): curve, colored sources and Karsten-style casting odds, how each land enters, opening-hand land counts, removal count, and a check that each sideboard plan balances. It opens automatically for a new deck or one with no matches.
• Synergy graph on every deck: saving a deck without edges builds a first-pass graph from Scryfall card text (lib/autoedges.mjs: what each card produces and which cards pay it off), stored in Notion under an # Auto-generated header. A deck with no edges at all (typed into Notion) gets the same graph on its page. Claude's hourly review replaces auto-generated edges with a reviewed, rule-based set.
• Plan profile: what each card does for you and against the opponent on seven axes (life, poison, mill, instant win; cards, board, tempo), read from card text (lib/axes.mjs). It shows the deck's main win axis, which of its costs are fuel, how hard every other deck in the tracker pressures your life (worked out automatically), and whether each self-harm cost is worth paying in each matchup.
• Jeffery Jones Fun Ranking (an extra, after a friend's axiom that a game holds a fixed amount of fun): a 0–100 index of how un-fun each deck is to play against, from card text (lib/jones.mjs): disruption, decision fatigue, annoyance and confusion, plus a "misery graph" of cards that compound each other. Leaderboard on the start page, details on each deck.
• Claude's deck notes: saving a new deck (or pressing Ask Claude to re-check) ticks Analysis Requested in Notion. An hourly Claude task in the project writes a pre-test review and synergy edges, then unticks it. A daily task reviews new matches. Both write the Claude Review field, which the app shows.

Reads are public; adding decks or matches, and removing matches, needs TRACKER_PASSCODE. Removing a match moves its Notion row to the trash.

Setup

1. Notion integration. At https://notion.so/my-integrations, use an existing internal integration or make a new one with Read, Update and Insert content. Open Pickpocket Match Log and Pickpocket Decks in Notion → ••• → Connections → add the integration to each.
2. Vercel. Import this repo (Add New → Project) and add the variables from .env.local.example.
3. Deploy.

Local dev

cp .env.local.example .env.local   # fill in the token and passcode
npm install
npm run dev
npm test                           # list parsing, stats and Notion mapping

Sideboard guide format

One opponent per line, Opponent | In | Out. Put your two hardest matchups first: the opponent table holds those two to a 35% bar instead of the deck's gate win rate.

Synergy graph

Each deck can carry a Synergy Edges list in Notion (also on the Add a deck form), one per line:

Rank Rat -- Tinybones, Pocket Nuisance | discard pings
Ambrosia Whiteheart !! Sheltered by Ghosts | bounce frees their permanent

-- is a synergy, !! a conflict. Only nonland main-deck cards count (lands are recognized from the Standard pool in lib/standard-lands.mjs). The page draws the graph and reports, in the same terms as the Claude project's Step 8 write-up: isolated cards, connected components (engines), cut vertices (single points of failure, and which cards they strand), λ₂ (algebraic connectivity), and the expected number of synergies with both cards seen by turns 4 and 7 (hypergeometric, on the play). It joins per-card degree with the dead-card flags from your matches. The math is in lib/graph.mjs, tested in lib/graph.test.mjs.

Installing on a phone

It's a progressive web app. On Android/Chrome, accept the install banner. On iPhone, open it in Safari → Share → Add to Home Screen. Pages you've loaded open offline; logging a match needs a connection.
