# Dataset Card for Dataset Name |
|
|
|
<!-- Provide a quick summary of the dataset. --> |
|
|
|
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](https://mtgjson.com), 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: |
|
|
|
```txt |
|
{ |
|
"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](https://huggingface.co./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. |
