Card Trivia:Spirit of the Six Samurai
- This is the first Union monster in a Generation 5 booster set.
- This is the first and only Union monster of the "Six Samurai" archetype.
- This monster is an older, post-mortem version of "Legendary Six Samurai - Shinai", according to the Master Guide 3 card storylines.
- This is also supported by the fact that both monsters have the same armor, Type, Level, ATK and DEF (barring a difference of 1000 for each).
- The Spanish Gladiator's Assault and Turbo Pack: Booster Five prints of this card have a typo, as the word "Unión" is printed as "Union". Its lore (in both cases) uses the correct spelling.
