For me it’s control priest. It’s honestly just one of the most unfun matchups for how much generation he’s got and healing and boardclears and I’d rather just auto conceelde at this point than face him. Doesn’t even feel good to play against him when you win
First place must be Control Priest. I know it is irreplaceable class identity at this point but it is firmly not fun to fight a deck that has copying (or even stealing) your own cards as a win condition, and besides that does not much but drawing cards and clearing the board two dozen times. If I play any kind of control deck I concede right there because it is an auto loss against my own stuff.
I also hate playing against enrage warrior, getting killed in two turns by a 30 attack remornia feels unavoidable.
As an enrage warrior myself lemme tell you my win rate is not good enough for you to be frustrated
And at least when i do win 90% of the time it’s by turn 6 or 7 in a short game
I’ll play 40 minute games against control priests and lose 90% of the time, now that’s torture
