I've actually got a few pauper decks I run.
There's UR Storm: http://deckbox.org/sets/525400
Similar to yours. This plays pretty consistently, although it's kind of a glass cannon. I strongly recommend Manamorphose in this deck; a free spell that pumps Cyclops + a cantrip is incredible.
There's BW Exalted: http://deckbox.org/sets/525401
First pauper deck I built. This one's fun to play. It's a really resilient deck, and it can play both the aggressive & control role. To me, it's a solid deck that can do multiple things at once. It has ways to stabilize & regain health, ways to control, and ways to be really aggressive.
And finally, UG Tron: http://deckbox.org/sets/525406
Somehow, it kind of works. Early game, it stumbles a little bit. But usually, by the time Tron is online, the opponent can't do a whole lot, aside from trying land destruction. Nessian Asp is such a great card for pauper, especially with Tron lands. It's easy enough to cast it before turn 5, but the Tron lands & Wildheart Invoker make it ridiculous. Fireball is a fun alternate win con.
I also have a pauper cube. I'll post a list eventually...
