It really wasn't ever useful to begin with. Before, it was typically one impact a game, if that, so this had a small timeframe to be used compared to other Secret Swords. Heck, the most used impact at that time would only be affected by it if the the caster had 3 or less life.

That said, I see this getting more use. Impact monsters will likely be played in decks that can use them and will be played at various stages. This being able to nullify the call itself will be helpful, as then the monster doesn't even hit the field.
