Trade Cards Online

Once per turn, you can equip this card to a face-up "Knight" or "Gardna" monster you control or unequip it to special summon it in face-up attack or defense position. Once per turn, during either player's turn, you can switch the battle position of the equipped monster. When the equipped monster is attacked while in defense position by a monster with less ATK than the equipped monster's DEF, destroy that monster after damage calculation. (A monster can only be equipped with 1 Union Monster at a time. When the equipped monster would be destroyed, destroy this card instead.)
