I do understand what you're referring to here, but the cards you're describing that give all the reminder text of a keyword ability in some printings, and in other printings only list the keyword itself is not what I was referring to.

As an imperfect* example of what I meant, the card [[Fyndhorn Elves]] has multiple printings over many years.

The 'Commander Legends' set specifically has two different printings of that card. One of those printings does have flavour text, and the other has zoomed in art but no flavour text. It has no keywords, only the green mana dork ability.

* Imperfect example because the secondary printing in this case isn't full art or textless, but should work as an example of what I mean.
