I'm happy to see you follow through with your opinion on Commander bans from the beginning of this year. My playgroup has gone completely the opposite way and banned a huge swath of cards that are only problematic in bulk.
To the best of my knowledge,
Panoptic Mirror is banned because filthy casuals were imprinting
Time Warp and similar cards for infinite extra turns, which is just as lazy and impractical as it sounds.
On the other hand,
Fastbond is part of a variety of infinite mana and infinite Landfall combos, especially with land-sac effects and
Crucible of Worlds effects. Releasing that will depend upon how reliable you believe such loops to be.
As a counterpoint I'd like some of your reasoning for certain unbans. I know you put it in the threads but there were several threads with posts of yours scattered throughout and making comments here would not only help organize it for me but would also help others find it IMO.
EDIT: I just remembered that
Storm Cauldron is the card that banned
Fastbond in Legacy. I have no idea how good that is in Commander, but I wanted to add it for context.
