heh, take a break man, or play some totally weird stuff with friends. The game is too much fun to be sad about.
As for competative decks, they change, but do so slowly. People have (valuable) experience in strong decks, they won’t let them go easily. But last worlds, we complained about NEH FA and how andy was always there. In fairness, clot changed something, but this last SHL final valencia and RP (but no longer the ELP-sentry monster) were common, and in the meantime butchershop and kate are (have been?) dominant.
And that’s just the tier 1 decks, tier 1.5 has moved around even quicker, and that within a year.
I think there’s hope for the meta yet, but it’s true, if you play enough, you keep seeing the same decks. In a month or two everything may be different
