This card can be used in "Chaos Dragon" Decks. Use this card's effect to mill a Normal LIGHT or DARK Dragon, and then use its secondary effect to mill a Dragon of the opposite Attribute, setting up for Chaos Plays. Discard "Eclipse Wyvern" to add another Dragon to your hand.
In a Gemini Deck, this card can send two Dragon-Type Gemini monsters to the Graveyard, so "Dragon's Mirror" can be used to banish them and Fusion Summon "Superalloy Beast Raptinus".
"Kidmodo Dragon", "Totem Dragon", and "Eclipse Wyvern" are excellent choices as Dragons with effects to activate after sending them to the Graveyard.
