@daniel-worobec I am working on the math now, though it's a little tricky given how many different things it does. currently I'm trying to think through exactly how the simulation should preference taking various cards over each other in what circumstances(should a second dredger be taken over a hollow one, etc)
Isn’t keeping 7 with this better than mulling to 2 with this in pretty much all cases? I don’t think mulling, with the intent of casting this spell, gets you any closer to finding something with it. The top cards of the deck are unknown in all cases.
Depends what your deck is doing. Dredge for instance would always mull a 7 hand with this in it and no Bazaar I think, because they can take subsequent mulls after that. It's not until they hit like 3 that they have to weigh if this is better or not, and in most cases it will be because even if you whiff you get 5 cards closer to what you need where as with mulls you would not.
A deck that plays in a more traditional way may not need just one card though, it is going to depend on the combination of things they have in hand, what they know about the opponents deck. etc. There will also be causes where people keep hands with this solely because it is a green card to pitch to FOV.
@vaughnbros the options are slightly dependant on what cards were kept earlier in the mulligan process of course when bottoming cards with ponder and then mulling the powder hand. in terms of what the average options are, given a 58 card deck where one bazaar and one OUAT are accounted for, that's easy enough.
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.
