Search this card with "Utopia Double" and use its effect to Summon "Number 39: Utopia". "Utopia" can then negate its own attack, resulting in a 10000 ATK monster.
This card can only be used if the last thing to occur was the attack being negated.
This card can also be used against "Magic Cylinder" because the attack negation and damage inflicting effects of "Magic Cylinder" are considered to resolve simultaneously.
This card cannot be used against "Scrap-Iron Scarecrow" because the last thing to occur was "Scrap-Iron Scarecrow" setting itself, and not the negation of the attack.
This is a useful counter to "The Door of Destiny", allowing you to destroy it before it can deal you damage/gain ATK by its effect.
"Legacy of the Duelist" can negate your own attack while destroying an opposing Spell/Trap. As it is a Continuous Spell, it can be used over multiple turns.
