Junk & Debris & Doppel... Tier 0?

This deck has been around for quite a while, since before I stopped playing. It's good to see it is going strong and has now evolved thanks to Doppelwarrior, Formula Synchron and TG Hyper Librarian. In fact, I think the deck should be called Doppel Librarian as those 2 are the key cards. I think Librarian should be banned while Doppel might get limited. The deck can still function without Librarian as you can see from the recent Singapore World Qualifiers 2011.

There is a prediction, by TeamPurplePanda, that it will top the Worlds. (Is the Librarian allowed?)
