[u]Basic Idea[/u]
Another user told me of a match he had against someone named "guywhowalksalone". The deck this person played used the synergy of changelings in combination with creatures that need as specific creature type on the battlefield. He liked the concept and shared with me. I also liked the concept and took the deck, to see which changes I would like to make.

[u]Tests[/u]
I have tested this deck against other pauper decks. The decks I tested against are a mixture of Control and Aggro and the result are recorded in a spreadsheet. If you're interested in details from the spreadsheet, feel free to ask.
