In episode 197, Leon von Schroeder uses this card during his Duel against Yami Yugi. He uses this card to destroy "Iron Hans" until his next turn. This increases the ATK of "Iron Knight" by 1000 due to its own effect. "Iron Knight" then attacks and destroys "Obnoxious Celtic Guard". On Leon's next turn, "Iron Hans" is returned to the field and this card is destroyed. The ATK of "Iron Knight" then reverts to normal.
