VISION is a Japanese dueling card game based on the Touhou universe.
Players tap "nodes" to play character, command, and spell cards to progress through the game.
Deck construction consists of exactly 50 cards with no more than three copies of each card.
Each player starts with 25 life, and players lose either when their life equals zero or they can no longer draw cards from their deck.
This is typically a two-player game, however there is a variant for a four-player game.
