...I really hate mass hexproof/shroud. Individual creatures is fine, but these things that make everything uninteractable just make a boring game. The fact this takes hexproof away from the opponent just makes it worse.
But good in commander.
This seems to me like unjustified hate. There are so many ways around hexproof, you can have mass spells that don't target, when it comes to removal things like sacrifice effects, stuff that selects types or qualities rather than targets, and so on. I think hexproof encourages people to introduce a wider variety of effects. Giving hexproof to creatures is particularly not as bad, since they are often involved in combat. I think it is more boring to have spells and abilities constantly super-reliable, always having viable targets out there.
My problem isn't with hex proof. it's with granting every creature you control hexproof permanently. Those answers aren't present in every color, are often not very good. Sacrifice removes your ability to choose, types/qualities effecting spells are often too niche, overcosted, etc. to be worth running regularly, especially when trying to deal with an army of hexproof creatures.
Individual creatures with hexproof, or all creatures with hexproof for a turn, don't bother me. Heck if your field is full of creatures that naturally have hexproof or got them from enchants or other creatures or what have you fine, you worked for that (in build and play), but cards like this are just boring and uninteractive.
