No official ruling on this card has been released, saying it cannot be used in Damage Step is incorrect until proven otherwise by Konami
* This card is useful for negating Graveyard effects that require a cost or can only activate once (per turn). However, this card cannot stop effects like "[[Blackwing - Vayu the Emblem of Honor]]" or "[[Treeborn Frog]]" which can be activated endlessly in the same turn and do not require a cost.
** Cards that require cost or can only be activated once: "[[Plaguespreader Zombie]]", "[[Glow-Up Bulb]]", "[[Sangan]]", "[[Dandylion]]", "[[Wulf, Lightsworn Beast]]", etc. But since it cannot activate during the Damage Step, some of these cases may not apply.
** Depending on the rulings, this card may be able to stop "[[Stardust Dragon]]" from protecting a card's destruction and may also be able to stop "[[Stardust Dragon]]'s" return.
