The first version of my Zur deck was a discard list, but it didn't really work and felt horrible to play against. I warn you, I don't think it's a good deck type for Zur, it doesn't close the game fast enough and sooner or later someone is going to find that Cyclonic Rift .
If you want to give it a look, here's the deck: Zur Discard Enchantments. It's a little outdated mainly in the mana department (both lands and rocks), but the enchantment side is pretty much there.
Hope you find some inspiration and build a deck that's not miserable to play and at a good power level.
