I couldn't agree more. Honestly chansey is a monster however no more of a monster than mienshao and zapdos. If one does not prepare for a top tier threat they will be punished. I don't think chansey was given a fair shake. As soon as she dropped people shout ban without even granting her a fair trial. I am on the fence on the banning of chansey. On one hand she is a filler wall that provides offense with a emergency in case a sweeper breaks one's momentum. This makes chansey quite a formidable force as she can immediately halt momentum while giving the trainer and opportunity to recover from what may have been a crippling defeat. While on the other hand chansey has revitalized stall while being hindered by it lack of offensive presence coupled with a heavy reliance on an item. I have found that Chansey has had a positive affect on the metagame but find herself to be a slight hindrance.
