so i got really tired of the standard game bc I've been playing on like, 3 different platforms, and decided to start trying to make the game easier because i found out custom games let you unlock stuff
and it turns out if you do a custom game with Sealed Draft and Vintage, you can pretty much guarantee you'll have a win. I haven't lost a game yet, and it's also got the really cool effect of just letting you build a pretty strong deck right away, which means you can get to experimenting with your cards/build much faster than standard.
It's helped me tremendously for learning about interactions and ways to play, you should give it a try!
