Top-Decking is the condition where a player is at a large disadvantage, such as having no cards on the field or in their hand, and draws a card that ends up turning the tables in their favor, usually for a game win. The condition is also known by players by the term sacking or luck-sacking, which is usually used in a derogatory manner. The condition is not solely applied to having no cards in the player's hand or on their field; it can also be applied when the player simply has fewer cards in their possession but draws a card that enables them to win.
Top-Decking has been incorporated into some Tag Force games as the Destiny Draw system, in which the player can nominate cards that can be drawn when low on LP.
