Oh, and as a side note? I'd love to see a weenie generation deck built around Stern Mentor.

This is quite nice. I think it'll be fairly effective, especially with Haunting Echoes and Traumatize. Here's my criticism, all pretty minor: You could probably replace the Skullsnatcher with a Tormod's Crypt or Nihil Spellbomb. A fewCall to Minds probably wouldn't hurt, if you think you could squeeze them in. Also, why are the Reliquary Towers in here if your only draw cards are the Treasure Hunt and Ninja of the Deep Hours? Maybe a card draw sabotage ability, like Neurok Commando has? When I get a chance, I'll send you a few copies of Curiosity so you can get more use out of those towers. Given that you have Gnat Miser in here, things that force 'target player' to draw cards could work well, too. As far as the ninjas go, Invisible Stalker (I know I pulled a copy when I was living with you, and it's not in any of my decks.) could work well as another ninja enabler, in case you can't pull your Levitation or Dimir Infiltrator. Neurok Invisimancer would work well too, if you've got him. Finally, what does NMS stand for? Ninja/Mill/Sabotage?
