To scoop is to surrender or forfeit a Duel, usually when a player knows for certain that they are going to lose. Scooping is often done to save time or hide face-down cards that would have been destroyed and seen had the player not scooped, which would give the opponent more information about the Deck during the next round. Scooping got its name because right after a player forfeits, they "Scoop" up their cards and shuffle them all back together.
Scooping proved a tactic against "Victory Dragon", as scooping only causes the player to forfeit the Duel, whereas the effect of "Victory Dragon" would have cost them the Match. As a result of this, "Victory Dragon" was classified as Forbidden to prevent players from causing conflict when scooping during a Match.
