In episode 22, Bastion Misawa uses this card during his Duel against Jaden Yuki. He activates this card after Jaden summons "Elemental HERO Wildheart" Jaden then points out that this card won't affect his "Wildheart". Due to the effect of "Litmus Doom Swordsman", its ATK became 3000 due to its own effect. Jaden then equips "Wildheart" with "Cyclone Boomerang", increasing its ATK by 500. "Wildheart" then attacks "Litmus Doom Swordsman". "Litmus Doom Swordsman" then destroys "Wildheart", but this activates the effect of "Cyclone Boomerang" effect, destroying all Spells and Traps and inflicting 500 damage to Bastion for each card destroyed this way. Because of this, this card was destroyed and Bastion's Life Points dropped to 0, winning Jaden the duel.
In episode 66, this card appears in a flashback Jaden has when he sees Wheeler as Bastion which makes Jaden remember his Duel against Bastion.
In episode 157, this card can be seen on the table of Ms. Dorothy's card shop as part of a group of cards that were thought to be defective by their owners (they were actually infected with darkness).
