Card Tips:Dark Core
- Cards like "Treeborn Frog", "Night Assailant" and "Necro Gardna" can make use of being discarded for this card's cost.
- This is another good card to counter against "Stardust Dragon", since it's effect only negates cards that destroy.
- Use this card to banish your opponent's "Ultimate Ancient Gear Golem" and prevent it to Special Summon "Ancient Gear Golem", since "Ultimate Ancient Gear Golem" will not be sent to the Graveyard.
- This card can also be used against a "Machina" deck to prevent your opponent from repeatedly reviving "Machina Fortress".
