Card Trivia:Wattaildragon
- A depiction of this monster appears in the artwork of "Ancient Rules", which is referenced in this card's flavor text.
- Its Level (6) and its ATK (2500) are also referenced in this card's flavor text.
- As "Ancient Rules" was released nearly six years prior to this card, this card is one of the few monsters to debut in the artwork of the Spell/Trap Card before being released as an actual card.
- This card's artwork and flavor text are similar to DRUMP, a 2013 one-shot manga released by Kazuki Takahashi about a blue dragon imprisoned inside a deck of magical playing cards for thousands of years.
- This is the first "Watt" monster that isn't a Thunder monster, the second "Watt" Normal Monster (after "Wattkid"), and the strongest "Watt" monster in terms of ATK.
