Really nice read and opinion on the matter.
Itīs a good idea to focus the metagame shifts on an wide analysis and now more than ever any list/tech/result widely spreads through geographically distinct communities. This maybe produced by the reduction of the numbers as players so we are forced to search for other sources of inspiration/information for our game.
Brian is totally right on his comment regarding the waste effects. I have to say we playtested yesterday with Long versus BUG without wastelands and the night ended with some strip effects added to the BUG decklist as a no brainer.
Keep up the good work!
Peach, I played a tweaked version of the list yesterday in a 19-man Vintage event in London. Finished 5th after five rounds of swiss. Never got to face Workshops or Burning Wish (though I did beat regular Griselbrand Oath), so can't comment on those match-ups, but it was a blast to play. Deathrite Shaman was awesome for me all day, burning several opponents to death.
Basically, I made the list more redundant going up to three Trygons, four snapcasters - and dropped the three Dimir Cutpurse for three Liliana. She was excellent - even got her a ultimate off a few times!
