; In order to be identified during a duel, the 60 cards of each duelist are given an index between 0 and 59.

; which, in turn, follows the internal order of the cards.
; This temporary index of a card identifies the card within the duelist's deck during an ongoing duel.

; Terminology used in labels and comments:
; - The deck index, or the index within the deck of a card refers to the identifier mentioned just above,
;   that is, its temporary position in the wPlayerDeck or wOpponentDeck card list during the current duel.
