It's like hedging for the 3% chance to see it. That said I can't imagine going below 2 Gempalms. It's the number two thing I tutor for. [Ringleader > Gempalm > Another Matron > The Rest]
Success has been reported with both 1 Piledriver, and 4 Piledriver, currently, they both have merits, and are one of the major points of contention in deck design right now. Do try both when you are starting out, finding the one that fits your playstyle.
Honestly, in my opinion, Crafter and Settler are traps. I wouldn't run them unless I was on a Warren Instigator list, as those can truly take advantage of them in one go. The classic shell requires simply more to go right when that comes down.
On singletons: Obviously the Matron Tutorbox is a wonderful thing, but going too deep lowers consistency in your average draw. Be wary of too many. Kind of like Traditional Elves versus Chaos Elves. One earned it's name for a reason.
Ya just don't need Vexing Shusher. Cavern of Souls solved that problem a long time ago.
Good luck, have fun!
