They just did real reprints of legacy staples. EMA was it, and it's really not a bad set at all.
I'm not some big proponent of the reserved list, but I don't expect them to change it. If they did, fine. And they DO care about every format, but the older ones tend to police themselves much more readily.
Given the bullshit around modern bannings, I'd much rather legacy continue to fly under the radar and get the support it does without a bunch of active meddling. When something goes totally wrong, sure, fix it. Mental Misstep, Treasure Cruise, Dig Through Time, etc. We aren't anywhere close to that with miracles.
