It seems like most of your issues are not with the Magic Arena client, but with the formats being played on Arena (namely Historic and possibly Timeless?).
If you’re into a slower, more methodical format, look into playing bo3 Standard and Explorer. Decks can still be explosive, but not as ridiculous, and typically the level of threats is about equal to the level of answers available in the format.
Alternatively, lean into limited formats. Draft decks will always require some personal thinking, every set is like a brand new format, and in limited, Tempo is key. Card advantage is key. Threats are key. Answers are key. Everything matters, and most people aren’t going to even have 4-ofs in their deck, so there’s a wider variance in cards seen. Plus, it’s a place where commons and uncommons can shine!
Also, I don’t mind when people copy decks. Some people are trying to learn how to play well and efficiently, rather than express themselves with deck building. One Standard deck I was playing last year was based on a Gruul Haste deck I saw on YouTube, and then I made it and modified it based on what I had and how many wildcards I wanted to spend. I ended up doing the same for a different deck I built in paper: start with a deck list, modify it based on what I have and how expensive buying the remaining pieces would be. I still brew my own silly decks, but there’s a reason that a meta can exist. Fine-tuned competitive decks are typically more consistent at winning than random brews.
As for my personal dislikes…
- The timer should exist in best of 1
Not just the rope system, but the chess clock. Maybe have it set to 20 minutes per player or something. It drives me nuts when I touch bo1 and realize that I’m spending so much time waiting, but I can’t quantify it. In bo3, I can hover over the timer and see that I’ve used up 3 minutes while my opponent has used 7, and at least feel justified in my impatience.
- Better deckbuilding and deck categorization options
Deckbuilding is frustrating. When I want cards that are green, it gives me all cards with green in their color identity, which I wouldn’t play in a mono-G deck. The search feature is slow and makes me wonder if my game froze up each time. Trying to move multiple of a card into the sideboard is multiple click-drags. The crafting interface feels barely slapped on, and makes it too easy for new players to accidentally spend their wildcards. And overall, while we have space for tons of decks, I really wish I could just save all of my decks, or at least a revision history of each deck so I didn’t feel the need to duplicate it along the way to have something to turn back to if my tweaks are bad. I turn to third party trackers for this functionality, but it should really just be part of the client.
- As a newer player, Draft was intimidating because it required a gem (money) investment every single time
I know this is how it works in paper Magic, but I really wish there was a way to draft and practice for free in the client. I know there’s DraftSim and you can get a group together on Discord, but that’s too much to ask of a new player. I don’t mind dropping a few bucks now and then, but the “stakes” of it all get me anxious and pushed me away from even trying it for the first year.
