I think the biggest issue with this game, besides no auto/squelch, is lack of skill decks in the game. Memorizing a meta deck is not skill.
The fact is that rarely does anyone who loses think it’s because the other player is good, but rather “lucky”. Which ultimately leads to gameplay dissatisfaction. I think this is due to the fact that the strongest decks in the game are easy to play. Sure you can play the game an unhealthy amount of time to memorize all the meta decks and strategies to give yourself an advantage, but each meta deck itself is rather simple to navigate.
In summation, more skill decks will lead to less toxicity and higher game satisfaction.
P.S. still need that auto-squelch please
