- This card can be searched by "Dark Sage", "Ancient Gear Drill", "Alchemic Magician", "Angmarl the Fiendish Monarch", "Left Arm Offering", "Watch Dog", "The Despair Uranus", "Synchro Fusionist", "Predaplant Chimerafflesia", "Sabatiel - The Philosopher's Stone", "Predaplant Darlingtonia Cobra", "Supreme King Gate Zero", and "Cyberdark Inferno".
- Use this card to send useful LIGHT, Aqua, Pyro, Thunder or Rock-Type monsters to your Graveyard to Fusion Summon "Gem-Knight Seraphinite", "Gem-Knight Amethyst", "Gem-Knight Citrine", "Gem-Knight Prismaura" or "Gem-Knight Zirconia". A few examples include "Volcanic Shell", "Treeborn Frog", and "Electromagnetic Turtle".
- It can also be used to easily search out "Gem-Knight Lazuli" by sending it to the Graveyard in order to use its effect and retrieve the "Gem-Knight" Normal Monsters.
- Discard "Gem-Knight Fusion" to recover your monster's ATK/DEF; afterwards, the effect of "Fusion" can be used to banish one of your monsters used as Materials for this card's effect to recycle it from the Graveyard.
- This card works especially well in a "World Chalice" deck in that it can be used to Fusion Summon "Gem-Knight Seraphinite" by using "Gem-Knight Lazuli" and "Lee the World Chalice Fairy" as Fusion Materials, triggering the former's effect and allowing the player to retrieve a "World Chalice" Normal Monster, and putting the latter in the Graveyard so it can be easily retrieved via its own effect later. The effect of "Seraphinite" is useful to further the plays of the "World Chalice" archetype, enabling more Normal Summons to put monsters on the field to use as Link Materials for their Link Summons.
