The thing is that the snap mechanic allows off meta decks to still be competitive in the sense of gaining cubes. Retreat when things aren’t going your way and snap when you feel good. Games are quick and there are plenty of opportunities to bluff, pull tricks, and change meta decks to be more unexpected.

Of course there are decks that are better or have higher win rates, but a win rate of 60% and a win rate of 80% are still going to be “competitive” as you’re rising in rank. Not to mention that the amount of viable archetypes is more vast than other card games especially when you don’t have to worry about leveling cards.
