[2022] Newcomer: did the new patch made all too "samey" or is it just a new meta?

Hey. I want to preface this saying that I'm relatively new to card games. I tried Heartstone and Yu Gi Oh, but neither pulled me in and felt that I had to invest too much in order to enjoy. But then, a month ago, I got into LoR and JESUSCHRISTITSSOGOOD

So yeah, I'm loving this game, but I can't help to feel that I've been playing against the same three decks for the last two days, which bums me out, cuz what I liked the most was the variety in decks and builds (even tho I know that metas, as in any game, tend to be very similar). What do you guys think?

Is it me being a noob or is this common for these types of games?
