The game has huge issues on both PC and mobile regarding it's loading times and general stability.
It's incredible annoying, that the game takes up to 5 Minutes to even load up and more than often you get stuck in "Entering Game" or "Waiting for opponent" or a huge list of different issues, that those 5 Minutes end up in 10 Minute waiting time without being able to play a single game.

This is super frustrating - especially comparing to competitors in the TCG Game sector (Marvel Snap e.g.).

It's nearly impossible or a little bit of roulette to "play a quick round of magic", because it more than often results in a frustrating experience.
