Cross Gear

A Cross Gear (クロスギア, in flavor texts often referred to as "magical weapons") is neither a creature nor a spell.

It is put into the Battle Zone similar to creatures, however it cannot attack since they have no power. When you choose to "cross" and equip it into a creature, you must pay the cost of the Cross Gear again, and the "crossed" creature gained the Cross Gear's ability. However when the creature is destroyed, the Cross Gear is not destroyed and remains in the battle zone.

There is no limit to the number of Cross Gears that can be crossed onto a creature, and the only way to remove Cross Gears from the battle zone is through effects that specifically affect Cross Gears.

You cannot fully unequip a Cross Gear from a creature unless the creature it is crossed onto is removed from the battle zone, or unless a certain effect does so. You can however choose to pay a Cross Gear's cost to transfer it from one creature to another.

When a creature crossed with a Cross Gear evolves or awakens, the resulting evolution creature or psychic creature also has the Cross Gear attached. The Cross Gear also stays on the base creature should the evolution creature lose the top card of the pile or the psychic creature is released.
