- Despite requiring Xyz Materials of an specific Attribute, which would restrict the usability of this card to WATER-based Decks, this card can be used in many Decks that have situational WATER monsters, such as "HERO", with "Elemental HERO Bubbleman", generic Rank 4-oriented Decks that run "Tin Goldfish" and/or "Jigabyte", and even Plant-based Decks, with "Lord Poison", thanks to the combo "Instant Fusion" + "Elder Entity Norden" .
- If this card was Xyz Summoned by using "Elder Entity Norden" as one of the Xyz Materials, its second effect can be used to revive "Norden", which in turn will Special Summon another monster and set up another Xyz Summon.
