They've just never really been a problem for me, and generally I wouldn't try to get myself into a situation where I'm taking on a full health Landorus with a Chansey. Like I said in my last post Counter is another option I considered but I just don't like being walled by a ghost. Can I please in turn ask why everyone thinks Gunk Shot is so appropriate. Greninja makes much better use of a special move like Grass Knot or even HP Fire.
