Siamese Neural Networks

Drafting is a game mode in collectible card games where players build their decks from a restricted pool of cards. Throughout one draft, players are offered a series of selections, from which they must build their deck. Although drafting is a popular game variant in \textit{Magic: The Gathering}, few machine learning models have been developed to learn card selection strategies. We model drafts with a Siamese neural network that is trained on real-world data and predicts human expert selection. Our model learns an embedding space of preferences by comparing cards in the context of a deck.
