I’ve always liked this question since there are (somewhat) definitive signposts for the meta at various stages of the game. I believe Dave Hoyland said in a podcast a while back that the “best” meta could be identified by the most “variety” and the most “skill intensive.” A best case scenario would be when those two categories would overlap.
From (if I recall correctly), Hoyland’s perspective from said podcast, some of the more competitive players enjoyed the CtM v. Whizzard Meta because, even though there was very little variety, the games were very skill intensive.
Having never played at a top table at a top tournament, I can’t really weigh in on that side of things.
For me, I think post-MWL of Worlds 2017 has been incredibly fun. Glacier and Rush seem to be viable option, Fast Advance in Weyland is kind of a thing; and I don’t see anything wrong with Good Stuff Anarch or Pirate Haley decks.
I’ve yet to play against the new iteration of Dyper (which won in New Zealand), which is fine by me.
While I think there is a place for a deck like Dyper in the game (same as there is a place for Wombo Combo CI decks), I hope those kinds of decks stay in the Tier 2/1.5 level
TLDR: I like the current meta a lot, but less so if Dyper surges to the top tables.
