• "Steelswarm Roach" and "Steelswarm Sentinel" appear in this card's artwork.
  • This card's artwork may be a reference to the notion that "Roach" is the adult form of "Sentinel".
    • The ring surrounding "Sentinel" resembles a "Vylon" artifact.

• The "Advance" in this card's name is a reference to an "Advance Summon", the OCG term for a Tribute Summon.
  • Oddly, this card (and therefore its name) was first released in the TCG, not the OCG.

• This card has a counterpart in "Trial and Tribulation":
  • Their effects are dependent on the number of monsters Tributed, and both of them were first announced as TCG exclusive cards.
