I was under the impression that The One Ring gave me virtual invincibility until my next turn after it enters the battlefield (if played), because the text when I hover over it says that a player with Protection from Everything "...can't be... dealt damage...," but apparently that is NOT the case, because apparently Questing Beast craps all over that. That would have been nice to know before I decided to play my copy of The One Ring instead of my Doomskar while my opponent had a Questing Beast in play. You should seriously consider changing the wording of the hover text on cards that give the user Protection from Everything to make it more clear that it "prevents" damage, rather than claiming that damage "can't be dealt," because it's confusing and causes things like what happened to me. I lost my game because I was relying on the hover text and I haven't dug into the minutia of the Oracle in a few decades (when "Protection from Everything" wasn't really a thing).
