I honestly don’t see a reason to ever unban them. These three have been proven to be unsuitable for the format, and if people really want to play them, I don’t see why they wouldn’t just be made available in Tier 4. Or some Tier that has no banned cards for the people who want to play that way.
Not to mention that these cards were the heart of the entire controversy that ended the Commander Rules Committee and caused the death threats to come out from some players. That alone would be enough to me to never bring these cards back to the format ever again.
Haha, I love that. Good lesson there lol
