I doubt I'd be of much good conversation but I'll chime in with my experience for the heck of it.
I was raised a Yu-Gi-Oh! boy, and had lots of good times playing with my older siblings decks in the family and stuff, but once I tried playing with other people in the local area I quickly grew disinterested, since the meta shifted to the new playstyles that were basically incompatible with the way we used to play and changed a bunch of stuff around (I speak mainly of pendulum and link, everything prior to that I didn't have much issue with).
Just a few months ago, some of my friends roped me into playing some casual magic with them after our D&D sessions, and while it seemed really intimidating at first with a lot of the talk going over my head, when I actually sat down and played a game with them for the first time (brutal initiation, mind you: 5-way commander draft that went until 4:30 AM) it wasn't nearly as scary as I thought.
I've played a bit more now, and have my own deck that I'm slowly improving off of a pre-con, so that's neat! I don't have any competitive ambitions for sure, I'm basically only playing the game since it's something my friends do in their free time and it's thus a way to spend more time with them engaging with their hobbies, so I don't plan on dumping a ton of money on it; just doing the bare minimum to have fun with the game and occasionally cook up something fun once I'm ready to.
I'll also mention that, despite only playing a small handful of games, I recently tried out the Dragon Ball Fusion World card game, and it's pretty solid! Fun and very approachable for people who are new to card games, and I definitely didn't need to know anything about Dragon Ball to enjoy it. I mainly tried it since one of my friends has been going professional with it and attending tournaments and whatnot (even helped start a podcast about it of all things).
So yeah, in most MTG conversations I'm the guy nodding my head "yeah" while the other 2 go on at length about the current meta and strategies for an hour, but I have a fun time with it. Some day I'll be able to play a full match without being babysat by my friend answering questions and offering advice, haha.
