Card-specific notes from database

• (Konami neuron) When activated from the hand, it is placed face-up in the Spell & Trap Zone. It can be activated this way during either player's turn.
• (Konami neuron) If the targeted monster's effects are not successfully negated at resolution (e.g., it is unaffected), the column negation is not applied.
• (Konami neuron) The column negation references this card's position at the time of resolution. Any Spell/Trap Card that exists or is placed in that column later that turn will have its effects negated.
• (Konami neuron) If a Spell/Trap in the negated column activates its effect by leaving the field as cost, its effect is still negated because it was activated in that column.
• (YGOResources) If a monster whose effects are negated by this card activates an effect on the field by leaving the field as cost (e.g., Tributing or banishing itself), that effect is still negated.
• (YGOResources) If a monster whose effects are negated by this card activates an effect in the GY, that effect is not negated.
• (Konami neuron) If the targeted monster is changed to face-down Defense Position, the effect negation stops applying.
• (Konami neuron) If this card targets a Continuous Trap treated as a monster, its monster effects are negated, but its Trap effects are not, so it remains in the Monster Zone.
• (Konami neuron) If the column negation applies to a Continuous Trap treated as a monster, its Trap effects are negated, so it is placed face-up in the Spell & Trap Zone (or sent to the GY if no zones are available).
• (YGOResources) If a monster's effect that changes the ATK/DEF or Level of other monsters has already resolved, negating that monster later with this card does not revert those changes. However, effects that only change the monster's own ATK/DEF or Level will stop applying.
