Dataset Card for Dataset Name

Text embeddings of all Magic: The Gathering card until Aetherdrift (2024-02-14). The text embeddings are centered around card mechanics (i.e. no flavor text/card art embeddings) in order to identify similar cards mathematically.

This dataset also includes zero-mean-centered 2D UMAP coordinates for all the cards, in columns x_2d and y_2d.

Dataset Details

How The Embeddings Were Created

Using the data exports from MTGJSON, the data was deduped by card name to the most recent card printing and aggregated as a prettified JSON object string (including indentation, which is relevant to embedding quality).

An example card input string:

{
  "name": "Marhault Elsdragon",
  "manaCost": "{3}{R}{R}{G}",
  "type": "Legendary Creature — Elf Warrior",
  "text": "Rampage 1 (Whenever this creature becomes blocked, it gets +1/+1 until end of turn for each creature blocking it beyond the first.)",
  "power": "4",
  "toughness": "6",
  "rarities": [
    "uncommon"
  ],
  "sets": [
    "LEG",
    "BCHR",
    "CHR",
    "ME3"
  ]
}

This JSON string was then encoded and unit-normalized using the Alibaba-NLP/gte-modernbert-base text embedding model.

JSON schema definitions:

name: Card name
manaCost: Card mana cost
type: Card type (full textline)
text: Gatherer card text. Exact matches to card names within card text are replaced with ~ for consistency.
power: Card power. Omitted if N/A.
toughness: Card toughness. Omitted if N/A.
loyalty: Card loyalty. Omitted if N/A.
rarities: List of all card rarities for all printings of the card. Rarities are listed in this order: ["common", "uncommon", "rare", "mythic", "bonus", "special"]
sets: List of all sets the card was printed in. Sets are listed in chronological order of printing. Basic lands have a special case of [*].

It took 1:17 to encode all ~33k cards using a preemptible L4 GPU on Google Cloud Platform (g2-standard-4) at ~$0.28/hour, costing < $0.01 overall.
