You can use Gearfried the Iron Knight and Mirror Wall if you like. Gearfried has the effect to destroy any equip card that is equipped to him. When Des Gardius attacks, activate Mirror Wall while Gearfried is on the field. When Des Gardius is destroyed, its effect activates to equip The Mask of Remnants. Thanks to Gearfried's effect, it can destroy it and returns your monster.
