Card Trivia:Proton Blast
- "Barrel Dragon" appears in this card's artwork.
- This card's name is based on the attack name of "Barrel Dragon" in the Yu-Gi-Oh! anime.
- This card's effect of destroying one card the opponent controls when two or more heads occur in a coin toss is an allusion to the effect of "Barrel Dragon" in the original Yu-Gi-Oh! manga and anime that gives it a number of attacks per turn equal to a number of successful roulette spins; Bandit Keith uses the effect in his duel against Joey Wheeler, where 2 out of 3 spins succeed and it battles and destroys both "Garoozis" and "Axe Raider" at the same time.
- This card's third effect is likely a reference to "Pillager", a Spell Card used by Keith that forced the opponent to reveal their hand and allowed him to take one card from their hand.
