Well in fairness Nick, I don't play this deck in legacy anymore but I use to when it could actually consistently win. I play dragon stompy, counter sliver and eva green mostly right now. However, this deck has always (in the past) gone well with my play style and therefore I am attracted to it.
Well Troop, considering this years Worlds hasn't happened yet and the metagame is anticipated on being similar to last years legacy format, which consisted of a whole bunch of threshold, top, storm and goblins being the most played. I fail to see how last years top Zoo decks that all sported river boas will be any different this year? Other then the fact there will probably be less Zoo this year at worlds because it has such a bad match against, tempo g/u/r threshold, dragon stompy, main deck belcher and top. With the top deck in the format and by far most the most popular deck playing blue (which obviously means islands) boa is tech. Also, with boa's regeneration ability against slogger, keg, deed and explosives, how is river boa truly a bad creature Troop?
I concur with you Nick and you made some very good and factual points.
