Cantrip

A Magic: The Gathering rules engine fast enough to train modern AI on.

Cantrip plays Magic exactly as the Comprehensive Rules write it, and quickly enough to play out and search the enormous numbers of games that today's machine-learning methods learn from.

A fast, accurate game of Magic in your browser comes along as a bonus: draft a cube with friends or bots, or bring a Standard deck.
