Im back!
Well I have to agree with Smite, it seems like Poison-types are being beaten to death still in Gen 5, and remember this is not Gen 6, so Poison is still as horrible as it used to be. So I might as well side with the fact that it may be saved, just maybe. Besides, its not OP, it looks like it can make Poison-types at least useful for the mons who get this.
