.....seriously? I don't think trying to fit a bunch of rogues into a goblin deck would do anything to help it in the current meta. I mean I guess if wall.dec is smashing face that works but iunno.

I'm using ambivalentducks deck as a platform, what would people recommend as replacments for the power (which I don't currently own)
 I was thinking of going
+3nullrods
+1 ssg
+1mountain
-3mox
-black lotus
-1crypt
This would allow me some more free slots in my sb to work on.

I think his post was more about how karn being an "answer" to inkwell isn't as important anymore now that sphynx is out here and that maybe he (karn) isn't as important to the deck.
 
I'm very interested in your results with SS, are you planning on posting a tournament report?

Do you really think that this is a possible replacement for DC? I understand that it gives you unlimited brainstorms but the fact that they aren't instant speed and aren't coming online t1 to help dig for mana/answers/whatever else you need is a big negative.
Comparing this to gifts seems kinda crazy that card was basically an "I win" when resolved. This while it might help you find one ( a wincon) doesn't really seem to be that kind of a finisher.
