H: Chapels, Gardens, Grindstone, Obzedat, More W: Wishlist, UWR Flash

So I'm trying to build UWR flash but I'm definitely willing to entertain all offers. I have several edh decks in the works (Radha, Ghave, Azami, Maga) so I'm interested in anything that would fit those commanders.
My priority wants are:
3 Snapcaster Mage
4 Boros Reckoner
3 Sphinx Revelation
4 Hallowed Fountain
4 Steam Vents
1 Sacred Foundry

I would prefer to trade higher value cards or staples for more of the same but if we are doing a bigger trade I can usually work something out.
Feel free to post trades here or go ahead and send me an offer and we'll check it out.
Thanks
