That wasn't my point. I don't see anywhere that says that the archery phase cannot be skipped.
Saying there is an archery phase after the maneuver phase implies that at the end of the maneuver phase, you have an archery phase.
Besides, the rules clearly state that you can't play a unique companion when there's a copy of that companion in your dead pile (contrary to
Sent Back), etc.
In order to argue that preexisting rules supersede the cards, you don't just need to explain how that allows
Anduin Confluence to work, you need to explain how
Sent Back,
Gollum, PD, or the many other cards that contradict the rules and yet have never been challenged work, just as I was able to give an explanation for the only case where a rule was deemed to supersede a card that directly contradicted it (OEG) (if you can come up with a case where a preexisting rule was interpreted to render part or all of a card's text entirely ineffective, I'd be happy to hear it).
Moreover, the question still remains why Decipher would bother to errata
Whisper in the Dark if the rules prohibited it from ever being played. Yes, they did that stupid errata with
Frenzy of Arrows, but that could be explained by the notion that they planned to make
archers or even forgot that there were no
archers, a far more understandable mistake than failing to notice that the card's game text explicitly contradicted a rule. Also, it could be that the errata to
Frenzy of Arrows was intended a backdoor ban, whereas the errata to
Whisper in the Dark would, by your interpretation, have absolutely no gameplay effect (since the card could never be played anyway).
What this keeps going back to, however, is the question:
When a preexisting rule would render part (or all) of a card's game text entirely ineffective, which wins? I would argue that the card wins, both because the card is later and more specific (so the general principles of interpretation favor the card), and because of the numerous examples where cards' game texts have been held or assumed to override preexisting rules (with no counterexamples of which I am aware).
