The reason people say vision doesn’t matter is because compared to a few years ago, it matters significantly less. Vision used to be the main determinant of PCI size before they created the inner and outer PCIs, but now only contact affects the most important inner PCI.

Cards like Finest Wisdom are actually usable on HoF despite low vision, whereas he would’ve been nearly impossible for the average player to use on HoF in a game like ‘17.
