A framework to evaluate any MTG deck

Not a decklist. A measuring instrument. Score decks on Data Density (I×W), generate tensors, and store runs in MariaDB. Works offline by default (annotations + names), and can be upgraded later with local oracle-text pipelines.

Offline-first no external calls required MariaDB store decks + eval runs Tensors 2nd/3rd/4th order exports Field strip Story/Hunt/Apex modes

What this site is

mtgdatadensity.thearchdaemon.org is your repeatable lab bench for deck evaluation. You can ingest a decklist, add (optional) annotations like role/behavior/mode, and produce:

  • Deck-level axes: DD, Intelligence, Wisdom
  • Dimension breakdowns (D1..D8)
  • Shape stats: entropy, singleton dispersion (Gini)
  • Tensor exports (including “overcommit/drain conversion” utility tensors)
Default mode is offline proxy scoring. Later, you can attach the local pipeline archives you’ve already built (Ollama/Scryfall cache) to enrich features with real oracle text.

Quick start

  1. Go to Admin and run the DB schema.
  2. Go to Ingest and paste a decklist.
  3. Open Report to view the latest evaluation.
  4. Open Tensor Lab for tensor tables + downloads.

Pro tip: use annotations to boost measurement fidelity. You decide the feature surface.

Scientific method loop

Hypothesis → Deck Variant → Evaluation Run → Tensor Comparison → Decision Rule → Repeat

This turns tuning decisions from vibe-based to reproducible.
