I like this card more in a redundant creature/hatebear deck with elvish reclaimer because you could find lock pieces or something like cavern on turn 1 for free. That seems huge in a deck like that at fixing the first couple turns while not being dead as a top deck on turn 7. Basically you get to have 7 cards out of the top 12 instead of the normal 7 out of 7. Seems great to me.
In regards to dredge decks. Is it safe to assume that you can take out Dredgers and put in some Once Upon a Time in place of those dredgers since it will find dredgers or and additional Bazaar of Baghdad? If so maybe 4x Shambling Shell, 1x Golgari Grave-Troll and 2-3 Once Upon a Time (maybe Hogaak too) may be enough to bring back Force of Vigor back to the Main Deck from the Side Board.

You are not casting them with mana, so unless you open with one after a bazaar they are just pitch fodder, unless riftstone portal falls in to favor in a big way.
I suspect the only time you take a dredger with these is actually when you whiff on finding another bazaar, so no I do not think you can cut dredgers in any substantial number to accommodate this as a matter of fact you likely want to keep the count high enough to ensure you hit one if you whiff on bazzar in the first place.
Have people not considered this for Hermit Druid decks? With the new Mulligan rule and this, getting a turn one Hermit (especially with 4-8 Guides) seems very strong.
I play a Hermit druid deck, and I'll be testing some number of these. Hermit druid decks can already mulligan aggressively, so I see this card as an interesting option.
A 2nd Leyline is literally a duplicitous effect or Bazaar fodder. The only thing a 2nd one dies is guard from single target removal (and FoV hits 2). There are few cards with lower value. This is not one of them.
Well, I don't generally plan to generate 1G, so maybe we have a little bit of a different framing here
