Card Trivia:Ice Dragon's Prison
- "Dragunity Knight - Ascalon" and "Trishula, Dragon of the Ice Barrier" appear in this card's artwork.
- This card's artwork is similar to the artwork of "Infestation Terminus", where a "Trishula" dragon is fighting a yellow dragon.
- While the battle depicted in the artwork of "Infetation Terminus" takes place above the windy "Shrine of Mist Valley", this card, in contrast, shows the battle during a blizzard.
- 'Snow and Sky' might refer to the Attributes of "Trishula" and "Ascalon", which are WATER and WIND, respectively.
- This card's Japanese name is based on the Japanese idiom 天牢雪獄 (Tenrō Setsugoku), meaning "the state of being buried in heavy snow and being unable to leave as you would in a prison created by heaven".
