- This card can be searched by "A Cat of Ill Omen", "Guiding Ariadne", and "Angel Paladin Arch-Parshath".
- "Guiding Ariadne's" Pendulum Effect allows the discard cost to be bypassed.
- This card cannot be used to counter monsters with Continuous Effects such as "Jinzo" or "Tyrant Dragon".
- This card can negate the activation of Effect Monsters' effects no matter where they are activated. Note that it cannot negate more than one activated effect at a time, even from the same monster. For example, "Pulao, Wind of the Yang Zing" has a Quick Effect that can be negated by this card. If this effect is negated, "Pulao" is destroyed and sent to the Graveyard, where its other effect activates as usual.
