Life (ライフ Raifu) is the zone to put the cards that represent a player "life" in the game. At the start of the game, each player starts with 4 cards in their Life. Life can be lost or reduced by damage dealt from attacks directed on empty Player Square or from a card's effect. Additionally, when a player decked out, they lose a Life after rebuilding the deck.
A player loses the game if their Life is reduced to zero at any point during the game.
