H: Standard Stuff N: Steam vents and Sacred Foundry

I need 4x Steam vents and 4x Sacred foundry. Some notable stuff i have is 4x Watery Grave, 4x Godless Shrine, 2x Obzedat. Ive got a bunch of other stuff, so check out my tradelist. I would like to get them as a playset. It would be fantastic to get all 8 in one trade, but otherwise i would like to get 4 at a time
