This card can be used on the opponent's Battle Phase to Normal Summon a monster whose effect could catch the opponent off-guard, such as "Dark Dust Spirit", or a "Monarch" or "Timelord" monster.
In a Dragon-oriented Deck, this card can be used to Normal Summon "Victory Dragon", after attacking with its Tribute fodders, unexpectedly ending the Match.
Due to their ability to Special Summon themselves from the hand/Graveyard, the "Dragon Rulers" can work very well with this combo.
