Actually I think Gherald's comparison is valid, in that both the draw variant storyteller and the pearl diver + cantrip + storyteller combo allow you to search 5 cards for treasures to discard (the latter looking through the 2 cards in hand, the card drawn by PD, the new top card and the bottom card). I think there's sone degree of disagreement about the strength of this scrying effect, though, where one side feels that there's a significant chance that the extra card searched is a treasure, and the bonus in that case is significant (extra cards drawn), while Gherald feels that the scrying effect is entirely negligible in the case when the extra card either isn't a treasure, or 3 treasures are already within the initial 4 cards. I suspect that Gherald may be underestimating either the bonuses gained from success case (picking up an additional useful treasure from the "pearl diver") or the chance of actually hitting the success case.
