Well I'm certainly not disagreeing that the dredge plan is faster when you have Bazaar in your opener, and you don't need to answer a hate piece, but the latter is extremely unlikely... You can't aggressively mulligan to bazaar game 2/3 or you will cost yourself a lot of games.
i have the opposite experience as this. in my experience when i have mulligand down to 4 cards in hand the bazaar, even if my opponent goes turn 1 RIP, is better as it allows me to start syphoning through my deck. the games that ive kept a 6 or 7 with multiple pieces of anti hate i have been punished as when my opponent sees i have no bazaar they just go on their merry way of doing what they want to do instead of trying to interact with me. the bazaar provides a huge psychology advantage as your opponent essentially is trying to answer a land, which unless they are on landstill or shops is going to be very difficult. if they are trying to answer a golgari thug and 2 bloodghasts without a bazaar they have more options and also less to worry about. i very much advocate an aggressive mulligan even in the later games, that being said there are some matches where going down to 3 cards in hand is just unreasonable.
