I see no such contradiction or inconsistency.
Stephen remarks that things that happen "every turn" happen on the turn of the player who controls the character.
Bryon remarks that "next turn" happens on the turn of the targeted player.
Those are the same thing.
Bryon also notes that under your interpretation, the card would do nothing UNLESS it were played in a side battle or multiplayer match.
Incidentally, that is the fate of False Dreams, but that's got different wording.well its understood to play like this- and then this card specifically says play it like that.
I don't know what you mean by this at all.
