Yeah, I cry in the face of hate, and then I hope that I can get an Incubator activated second turn and win third turn before the hate has a chance to really hurt.
I have considered Spellbombs, the Slith, and the Worker. I'm going to try the Worker and see how that goes. It certainly will help the mana curve (which is just ugly right now, although it was uglier before the Ravagers went in).
Generally, I didn't find the two Spellbombs that useful, although I do have some of each in the SB. They might still find their way into the MD, though; I have to play it some more. Speaking of which, the SB currently includes some Elf Replicas, Goblin Replicas, AEther Spellbombs, and Pyrite Spellbombs; I haven't finished it yet, and it isn't that high on the list, given that the deck is casual.
Yeah, this is basically a bad version of affinity. I like being able to sit down with a stack of 60 artifacts, though. It's just neat.

Thanks for the comments. I'd forgotten about the Worker.
