This monster can only be Ritual Summoned with the Ritual Spell Card, White Dragon Ritual. You must also offer monsters whose total Level Stars equal 4 or more as a Tribute from the field or your hand. When this monster attacks a face-down Defense Position monster, destroy the face-down monster immediately with this card''s effect without flipping it face-up or damage calculation. You can Special Summon 1 Blue-Eyes White Dragon from your hand or your Deck by offering this card as a Tribute during your Main Phase. (Blue-Eyes White Dragon cannot attack during that turn.)
