** 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.
