• 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. As "Iron Hans" is no longer on the field, the ATK of Leon's "Iron Knight" returns to its original value. "Iron Knight" then attacks and destroys Yugi's "Obnoxious Celtic Guardian". On Leon's next turn, "Iron Hans" is returned to the field and this card is destroyed. This causes "Iron Knight" to lose 1000 ATK due to its own effect.
