This is one of the best combo ever created by Seto Kaiba.Saggi the dark clown and the crush card virus.The crush card infects another player's deck by making sure monster with less than 1500 attack power can be used anything over and the monster is destroyed.Meanwhile you can bring out a blue eyes and destroy the opponent.The crush card virus requires that you sacrifice saggi the dark clown.Saggi does not need to be destroyed by an attack.
