I continue to convert my Brawl builds to Standard builds. Here is the TappedOut list:

This was a momentum win.
Here is a 'lessons learned' loss. I seemed to be poised for a win...
...and then Guideon dropped.
And after I got rid of it, I once again seemed poised for a win.
...and then my opponent took over my strongest critter.
I had to chump block with Marwyn.
And then I top-decked lands for a few turns while my opponent drew good stuff and beat face.
