Card Trivia:Hi-Speedroid Puzzle
- This monster appears in the artwork of "Speedroid Dupligate".
- This card's Japanese name, "High-Speedroid Sharp Sword Spy Zule" (
HSR 快 刀 乱 破 ズール Haisupīdoroido Kaitōrappa Zūru), is a pun on "puzzle" (パズル pazuru) and the idiom kaitōranma wo tatsu (快刀乱麻を断つ), which basically means "cutting the Gordian Knot" or, in other words, "to solve a difficult problem through a simple direct answer".- Fittingly, at the start of the Damage Step, this card can make ATK become double its current ATK until the end of the Damage Step, if this card battles a Special Summoned monster.
