Inside the 1.5 Metagame, 1.5 RDW

In about a month our local store is having a 1.5 tournament for a unlimited mox ruby. I won't get into the politics of how it ended up that we are having a 1.5 tournament but lets just say there were some. However I'd still like to represent and win this tournament so let try to get some discussion.

IMO Bazaar owns 1.5. Madness or Dragon lose the least when translated to 1.5 and I'm fearing both. I really can't play either because I don't own the bazaars.

What other decks are there out there, has there been any other recent T1.5 tournaments out there?

Just to add a few things I've been working on a 1.5 version of RDW with goblin welder, check it out.

The big difference from the traditional extended RDW is the Goblin Welder. He is used to recur Tangle Wire. So far playtesting has been quite favorable but I'm curious if there's some one out there with there ear to the street on the 1.5 metagame and how this would stand up?

Thanks
