Angry Grimace
Two cannibals are eating a clown. One turns to the other and says "does something taste funny to you?"
Again, the bar is already pretty high. If they can't not print a 1CMC +7/7, then okay. Maybe we look at banning that card. But despite the feelings on Become Immense, it quantifiable hasn't broken the deck. The deck continues to be barely played in any real sense.
And they can absolutely print "All my creatures have double strike." They have. With infect, it wouldn't even fit in any version of the deck and would have to be costed so low as to break any aggro deck. Temur Battle Rage is what you're really talking about, as with infect "all creatures" really means "the one creature I have." But it hasn't even warped the limited infect meta to allow for red to be splashed.
And that last point is exactly why it's an 8 on MaRo's scale and that's nonsense. People hate counters, so we get crap control decks. People hated Annihilate, so we got whatever the hell is going on with BFZ. People hate basically everything that's new or different or isn't big, battleship Magic. If we start banning stuff because "people don't like playing against it" then Magic will be solitaire.
Because the real thing people hate is any deck, archetype or card that causes them to lose. Infect isn't Eggs. It isn't Volt Key. It isn't even Storm pre-Seething Song ban. It's a one trick combo deck that more often than not dies to Path to Exile or Bolt.
Case in point.
I honestly have no idea what you are talking about at this point.
