The following unrestrictions would have made much more sense to me:
Mox Diamond
Dream Halls
Fact or Fiction (mentioned afore)
Frantic Search
Personal Tutor
Time Spiral
Grim Monolith
Fact or Fiction is the only card on this list that would actually see play. If they had unrestricted the others it would have been 'safer' than what they did unrestrict, and helped clean up the B/R list, but wouldn't have actually changed anything. Instead they've given us a new format. Is a 4x Gush format going to be fun? I don't know, but I'm looking forward to it.
