i wouldn't call eviolite chansey an overly effective wall. hell, i wouldn't even call it an effective wall. it's already setup on by so much, and lack of leftovers means it is having to heal constantly which gives the opponent more time to setup. most of the times i've had any reason to run chansey i'd run leftovers just to the prevalence of hail/entry hazards. chansey isn't this unbreakable wall people are making it out to be.
Too much sense in one post.
