- This card can be searched by "Dark Sage", "Ancient Gear Drill", "Angmarl the Fiendish Monarch", "Left Arm Offering", "Terraforming", "An Owl of Luck", "Demise of the Land", "Ancient Fairy Dragon", "Madolche Butlerusk", "Favorite Hero", "Planet Pathfinder", "Pop-Up", "Set Rotation", and "Archfiend General".
- This card lets you choose which "Archfiend" monsters you want to pay LP for, and which ones you don't, essentially making the effect of "Battle-Scarred" optional.
- Use "Hate Buster" to destroy a monster attacking an "Archfiend" along with the attacked monster and inflict damage, while searching for a lower Level "Archfiend" using this card's effect.
- You can trigger this card's effect with cards that destroy themselves or other Archfiends, like "Mist Archfiend", "Cyber Archfiend", "Archfiend's Roar", "Archfiend Commander", or "Archfiend Emperor, the First Lord of Horror".
- When you search your deck for an "Archfiend" with this second effect, you can choose one whose Level complements that of a Tuner you have to make it easier to Synchro Summon.
- Equip one of your "Archfiend" monsters with "Synchro Boost", so that if that monster is destroyed you can add to your hand the same one or a different one of equal Level.
- Because of the great searching powers of this card, you can select the right "Archfiend" in a lot of situations. For example, if you have "Terrorking Archfiend" on your side of the field, you may want "Desrook Archfiend" or may want to protect it with "Vilepawn Archfiend", especially if you can power up your "Vilepawn Archfiend" with "Infernalqueen Archfiend" or "Imprisoned Queen Archfiend".
- This card is needed to be able to Special Summon "Mazera DeVille".
