I wouldn't run coffin purge. Surgical effects are way more powerful vs ANT and dredge (and pretty much everything else I can think of that we would bring in yard hate against). Removing ALL the copies and potentially taking cards out of their hands is generally more powerful than either removing two cards or being able to entomb it.
Peace
I don't disagree and is why I suggested keeping both copies of extirpate. It may not be worth he sideboard slot.
Laser Brains, I like DC too but as it is I'm working on this version right now. Thanks though!
Dromar, I went and got two SDT and four Bloodstained Mire. Turns out that, yes, they and Entomb are very useful in conjunction with the SDT, allowing for finding that key card. Also I decided you're right about overkill with the Ratchet Bombs versus Lily, so I switched the sideboard a bit and have actually taken her out for a few games, when anticipating Needles. Twice I got people to name her, to no avail I did maintain the 4 Bombs though, as there is a heavy presence of Tarmogoyfs, Deathrite Shamans, Kird Apes, Wild Nacatls, Glistener Elves, etc. at my shop.
In the main 60, I wanted to try 2 Racks and 2 Shrieking Affliction to lessen the vulnerability to dedicated artifact hate like Smash to Smithereens and Ancient Grudge. I know plenty of cards can take care of either of them, but I figure the off chance of catching someone with an anti-artifact card in their hand cause they saw The Rack last game, but having Affliction working them this game would be great.
I like a Coffin Purge in the sideboard. I'd keep the 2 Extirpate as well. I'd also consider 3 The Rack and 1 Shrieking Affliction or 4 The Rack and 1-2 affliction sb. It's probably a meta decision, but I think making sure that game 1 is as good as possible is important.
