Doesn't work the way you might hope. Pokemon of this type would hardly ever be used, but everything would use attacks of this type. Like how Ice types are pretty bad in general and don't see much use, but Ice attacks are everywhere.
Unless you restricted attacks of this type to Pokemon that have it. But even then...
I'm probably giving way too much thought to this.
I summoned a baby to attract a lion. It didn't seem to work, so I tried a delicious baby. Regular baby ATE delicious baby. Horror....horror.~Gameplayingperson
