Fusion Deck Zone

From Yu-Gi-Oh!

Box 4 is where your Fusion Deck resides face-down at all times. While obsolete in the OCG & TCG, it is still used in a multitude of Video Games.

In the OCG and TCG, the Fusion Deck was renamed to Extra Deck, due to the inclusion of Synchro Monsters. Subsequently, the Fusion Deck Zone has now been replaced by the Extra Deck Zone.
