Cutting Breakthrough is wrong, and while I realize having 12 Dredgers and 12 Gold Lands is optimal in terms of mulligan criteria, I think it's difficult to calculate the value of Putrid Imp, and to a lesser extent Tireless Tribe, in place of the 12th Dredger or 12th Gold Lands because being able to discard your entire hand, use your draw step to dredge and guarantee you have a Dredger in your graveyard for your draw spell and play around Tormod's Crypt has merit that's incalcuable.
I can't even figure out what the trade off is between a Golgari Thug and a Gold Land actually is, like Anusien said it feels like having to choose between cutting off a hand or a foot, is the 12th Golgari Thug more important than the 11th Golden Land when the Golgari Thug has a worse return on Dredge (4) compared to Tarnished Citadels equal return on mana (3 damage is irrelevant IMO)?
Maybe the post-board Griselbrand should be a Golgari Thug, worrying about having an alternative Dread Return target in case of Golgari Grave Troll being RFGed may be anal retentive considering putting 3+ Zombie Tokens on the board and either an Ichorid to activate Bridge from Below again at end of turn, a Putrid Imp to discard your hand, a Golgari Thug to sacrifice to Cabal Therapy and stack a Narcomoeba on top of your deck or just a Stinkweed Imp to chump block all have merrit.
Hmm, maybe not playing the 12th Golgari Thug is a personal leak of mine, but RAWR Griselbrand ...
