Obelisk the Tormentor (original)

The following are the effects as translated from Japanese:


 * You can activate this effect during you or your opponent's turns. Sacrifice two monsters other than Obelisk on your side of the field. Until after Obelisk attacks, its ATK becomes "∞" (infinite)
 * In addition, all monsters existed on your opponent's side of the field receive battle damage of an amount equal to the current ATK of Obelisk.
