>The poison status effect cuts special attacks. in half.

So I hear about this a lot and I think it is a smart idea to have a status effect that cuts special attacks in half, similar to how burn halves physical attacks. However, poison is too common of an effect, too many pokemon learn toxic and it would completely destroy every competitive special attacker. But what if we added a new status effect into the game, specifically to cut special attack in half and hurt the pokemon over time?

Discuss which type needs this buff and what the new status effect is called? What are the implications in the metagame? Are powerful special attackers in Ubers crippled by this?
