New Ravnica effect copies are castable immediately [Investigating]

Tilwin90

The Dimir (first) node from the new Ravnica event has a Cipher support that copies non-copy spells and grants them mana equal to the power (or toughness? can't remember) of the first creature on the board. This all works fine. What's interesting is that these copies are castable the same turn!

I double checked to ensure the cards are seen as copies, and they indeed are. They had the small copy symbol. The description also suggests they are copies, and it's in no ways different from Thousand Years Storm. 

I went further as to try playing TYS in a separate match. Well, you can imagine my disappointment when I noticed its copies are not castable the same turn.

So I reopen the can of worms here and now. What's going on? Based on what rules are copies castable the same turn or not? The current approach to eliminate infinite combos seems to have lead to some super random and undocumented (via card text!!!) behavior of copies. Is this just a flag the devs decide to put on the various effects as they see fit? It would seem so as copies everywhere don't behave the same.

N.B.: I am posting this in the bug section as I am realistic enough to assume that the Cipher implementation is a bug, and not some means of trying to be more permissive about casting copies the same turn.

Thank you for reporting this. I'll relay this to the team for investigation. According to my information, Copies being unable to be cast on the same turn is still the intended functionality.

For what I heard from a friend Jaya copies can be cast the turn they a created too
