As this card destroyed a Defense Position monster his opponent controlled, Kaiba then Tributed this card to Special Summon "Blue-Eyes White Dragon". This monster is later seen when Kaiba counts the number of Dragons in his Graveyard when "Deep-Eyes White Dragon" uses its effect to inflict effect damage to Yugi. On the last turn of the Duel, this card is banishedfrom Kaiba's Graveyard when Yugi activates "Final Geas".
