I have spent far too long playing Magic Arena when it’s really just awful in pretty much every way you can imagine.
The economy is unbelievably broken because randomised packs are the only direct way you can use your gold to get cards, and they’ll almost never have the cards you need or in the quantities you need to have a halfway competitive deck.
Wildcards do allow you to choose to redeem them for specific cards, but they have to be of the same rarity as the wildcard and the mythic and especially rare wildcards you need so many of are always in short supply. Getting anything decent without spending real money requires a ton of grinding. I honestly wouldn’t even mind having to spend money if I could just buy the cards directly like in Magic Online, it’s much jankier but in my opinion better predecessor, but you can’t.
Probably the best part of the game is just the digital implementation of the game mechanics, but even there are some seriously annoying issues which come up not infrequently and can lose you games (like the autotapper for some reason valuing 1 life over keeping an extra colour of mana open for responses).
Overall it just feels like 95% of the time it’s just me grinding playing games with fast aggro decks I don’t even enjoy (I’m into control but it takes way longer to get your rewards that way). It’s just so so much worse than the paper game I love and I don’t think I would ever play it if it weren’t for the fact playing in paper is stupidly expensive for pretty much any 1v1 competitive format (commander is great and all and I have a couple decks, but it’s not my preferred format).
