First and foremost, this card is useful during the opponent's Battle Phase, preventing them from attacking any further that turn (with some exceptions). As a result, it renders those monsters vulnerable to counterattacks during the next turn, especially if they have low DEF values.
With this in mind, cards with piercing-enabling effects are ideal to use afterwards.
This can be useful in "Morphtronic" and Clown Control Decks, since it simultaneously interferes with the opponent and enables one's own card effects.
This card is also useful for avoiding the effects of opposing card effects, such as "Mirror Force" and "Hammer Shot".
