- In episode 103, Dextra sets this card during her Tag-Team Duel with Yuma against Nistro and Alito while the former was brainwashed by Alito. In the next episode, this card is switched to Attack Position by the first effect of "Battlin' Boxer Cheat Commissioner", which also subsequently forces "Number 54: Lion Heart" to attack "Number 39: Utopia". Dextra then activates "Butterspy Courage" to redirect the attack to this card. Due to the second and third effects of "Lion Heart", it is not destroyed and Dextra takes the same amount of damage Nistro takes. Nistro then activates the last effect of "Lion Heart" to make his Life Points 100.
