So what? If you're running a deck that depletes your hand alot then yes go for Bianca, If not then run PONT with Copycat or Cheren. It's not perfect by any means but at least you're getting a good draw out of it. Cheren is just an upgraded version of Mom's Kindness from the last 2 formats and not very many players ran that card at all.
Copycat is just as conditional as Bianca is because If your Opponent is low on hand size and you need a bigger hand then it won't do you any good. Bianca makes up for that by giving you hand refreshment, just test it out and see what I mean. It's foolish to label a card as bad unless you've playtested for yourself. I've tested Copycat and while it helps it can also hurt as well.
