Has there ever been some consideration of taking a few of the cards that basically don't work in the rules, ones that have persistently needed whole sections, stuff like Panglacial Wurm, and shifting them into the Falling Star/Shahrazad and such category, cards just deemed... Well, you know. Basically, "we shouldn't have printed this card and every rules-manager's job gets harder because of it, so now it's gone forever"? If a rules-manager proposed that, would they succeed?

There have been a number of calls to ban Panglacial Wurm in every format for rules reasons (aka it doesn’t kind of technically work).

In the same way that silver-bordered cards from the past can be de-acorned (though there are no current plans to do so), is it possible that cards like Chaos Orb, Falling Star, or Shahrazad could be removed from the ban list and acornized? (I'm not talking likelihood, just theoretical possibility.) Still unplayable in Vintage, Legecy, etc., but a format like Commander+Acorn would then have access to them. Thanks.

Being there’s no Chaos Orb printed with an acorn and we can’t print one because of the Reserved List, it seems an odd move. Also, as with Chaos Orb, there are some play design issues.

Dexterity cards? What are those?

The two most famous dexterity cards are Chaos Orb from Alpha and Falling Star from Legends. Both cards required you to hold the cards at a certain height at drop them. They affected the cards the cards they touched when they landed. R&D has decided to no longer do cards like that with the sole exception of silver-bordered cards.
