- If this card and "Bad Reaction to Simochi" are both applying, any effect that gains LP will gain LP, and any effect which inflicts damage will inflict damage.
- The ② effect can be activated during the Damage Step, as it negates activations.
- The ② effect cannot be chained to effects which are not guaranteed to destroy a monster(s), such as "Snipe Hunter".
- The ② effect cannot be chained to a "Royal Oppression" which is negating the summon of a monster not already on the field, such as the summon of "Cyber Dragon".
