The biggest for me was that everyone felt like they were all drinking the same coolaid, as in 95% of the player I met played type 2.

As a student at the time I couldn't afford to continue buying the new expansions to follow the meta and quickly saw type 2 as a brilliant mechanism to keep everyone buying new cards. As a person who'd played and collected cards from all sets for close to 10 years it felt like I had enough, duals lands, amazingly powerful cards that I couldn't use with anyone else I met... No one wanted to play their new modern competitive deck of the month VS my type 1 powerhouse.

And yes I get that type one was prohibitively expensive for new players to try, it's that disconnect between me and everyone else led me to quit. Sell all my cards on ebay for a grand at least and regret it later and the cards seems to only have skyrocketed in value since.

IDK, Magic Arena is quite popular, and I know a lot of people who got into it somewhat recently, so it's still a good game. Mana screw/flood is annoying, but it infrequent enough that it's not super frustrating.

I quit because I just don't have the time to keep up with the pace of expansions, and if you don't have top tier cards, you'll probably lose. I like the gameplay, but not the collection aspect, especially since the trading aspect is dead online.
