Still, though, 1st place with 64 players consistently? I am assuming a good chunk of the 64 are running these "meta decks" as you call them, right? Not sure if impressed or scared.
I generally main deck to counter the number 1 expected deck, plus play generic counters to soft counter meta and non meta. Sideboard to counter the 2nd and 3rd most expected.
People playing anything below that more often than not aren't very skilled, or are playing antimeta too, so the match up is decided by who knows how to play the deck better.
That's what's worked for me rather well for a number of years.
Alan, get me pizza too please.
