Why can't this Chansey participate in free battles?

So Ive been using a Chansey on my team for a while now, and recently I went on Powersave to change its EVs, nature and IVs. So I know its not my hacking technique because I use this on every other Pokemon on my team and it works… Im going to post the full stats of her so that we know exactly where I went wrong…

Heres my Chansey, what makes it unusable in free battles?

Whats wrong and how does free battle figure out that she is hacked?

Okay, using the Pokemon Showdown Simulator for Team-building I’ve discovered that there is no possible way that your EV/IV spread could yield those stats. HP is correct, as well as Defense but somehow the rest are messed up.

With perfect IVs going straight down and max EVs in HP and SP. Def, and four in Def, your Chansey’s stats should look likethisat Level 100.

When you Powersaved it somehow it gained improper stats. This answer is based off what information you gave, as this is seemingly the only problem. Powersave another and see will you have the same problem.

Hopefully I’ve Helped
