-Stuff-

I think Forbidden Lance will work really well in GB's when it comes out (shortly).

You do have a pretty good build here overall. I might quibble a bit with a few of the card choices, but it would probably come down to personal preference.

This is a pretty good idea, actually. Having a bunch of basic decklists as references for folks.
