- This card can be searched by "Dogu", "Single Purchase", "Temple of the Kings", "Transmodify", "Rescue Ferret", "Horus the Black Flame Dragon LV4", "Level Up!", "Ninjitsu Art of Super-Transformation", "Dragonic Guard", "Draconnection", "Blaster, Dragon Ruler of Infernos", "Tempest, Dragon Ruler of Storms" and "Hieratic Dragon King of Atum".
- This card can be Special Summoned by "The Flute of Summoning Dragon", "Red-Eyes Darkness Metal Dragon" and "King Dragun".
- "Gilasaurus" and "Dynatherium" can be Tribute fodder for this card and provide a monster for this card to destroy by battle (and then level up).
- Use with Spell Cards that would affect your monsters such as "Dark Hole", "Mystic Box", "Nightmare's Steelcage" and "Messenger of Peace".
- "Level Up!" and "Level Modulation" do work on this card despite its effect; "Level Up!" sends this card to the Graveyard as a cost, and this card's effect only makes it unaffected by Spell Cards while face-up on the field.
- There are occasions where you may not want to level this card up right away, as while "Horus the Black Flame Dragon LV8" can negate Spell Cards, it is still affected by the effects of Spell Cards already on the field, such as the aforementioned "Messenger of Peace".
Traditional Format[]
- This card can be searched by "Guardragon Elpy".
- This card can be Special Summoned by "Premature Burial" with no drawbacks, as "Premature" taking the equipped monster with it when destroyed is a Spell effect.
