@serracollector Agreed, Serendib Djinn has similar wording to Drop of Honey which has thankfully been un-errata'd to almost go back to doing what it always did. Drop of Honey should still be destroyed instead of sacrificed when there are no creatures to remove any confusion people might have when making it indestructible doesn't work because of some arbitrary and unnecessary errata. Only because "discarded" translates to "destroyed" in all other contexts.
As has been pointed out in another thread the Djinn was originally intended to function with two cards that make lands indestructible and has historically been used in conjunction with at least one of them (Consecrate Land) in competitive play. The Keyword sacrifice was already properly templated when Arabian Nights was printed which means it was intentionally not used in that card's text so current errata does not reflect the originally intended purpose of the card. The only ambiguities in that set regarding destroy effects are related to the words "discard" and "discarded" which, as far as I can tell, have been updated to "destroy" and "destroyed" in all other contexts.
There is also the issue of the few cards with the pseudo Islandhome mechanic which, again, has been replaced with sacrifice instead of destroy. The issue there is that these cards haven't been errata'd to use the Islandhome mechanic so there is no reason for them to have the change of wording to comply with the templating for a mechanic that barely even really exists anymore. Even the most recent printing of Island Fish Jasconius uses the keyword "bury" which translates to "destroy without possibility of regeneration" in every other context. Diamond Valley and Metamorphosis both use the term "sacrifice" so there is a distinction which is visible on the cards themselves in every possible context.
There's absolutely no reason for any of the affected Arabian Nights cards to do anything other than what is printed on them anymore. Once upon a time there was I'm sure but the modern rules properly accommodate the wording of almost every card in Arabian Nights today. Some of them have been updated to work as they are printed and others have not been. There doesn't appear to be any reason for this discrepancy that I can see except maybe laziness which is to say that they just overlooked it and it's all just an accident.
With the advent of Old School it makes a lot of sense for Wizards of the Coast to restore the original function of as many of these cards as they can.
