[u]Basic Idea[/u]
I've played some testgames, using a dimir mill deck (which isn't really good or balanced to be honest), and the most serious problem I had there was, that the deck was far to heavy into mill and lacked options to stop an opponent from attacking. So I decided to make a different approach and use defenders in combination with Doorkeeper and some slower mill-cards that I felt where good and powerful enough. This didn't work out really well, as I had to few defenders and they weren't able to stop an aggressive deck from overrunning me. So I did some changes and added Dimir Infiltrator to be able to tutor for Jace's Erasure.

[u]Tests[/u]
This is one of the decks I'm using as benchmark, to test my other Pauper decks against, the result for each test are recorded in a google-document spreadsheet and added to the description of each of my pauper decks. If you're interested in details from the spreadsheet, feel free to ask.
