Need Dredge small stuff and lands

I've had a lot of luck in finding trades for larger stuff and I'm hoping that finding this smaller stuff goes just as smoothly. I need:

4x Narcomoeba
2x Breakthrough
4x Careful Study
3x Stinkweed Imp
1x Golgari Thug (looking for IvG duel deck version)
1x Ichorid
1x Flame-Kin Zealot

And the lands:

4x Cephalid Coliseum
4x City of Brass
4x Gemstone Mine
1x Undiscovered Paradise

If you have any of this stuff, and can come up with a trade, please let me know.

Thanks,

Art
