Is mmr even working? every opponent is unbeatable imbue or murloc paladin

hi, i’m not a good player and i don’t play much so i usually only reach gold 10 each month while doing my quests.

but ever since the paladin imbue deck was buffed it seems like 80% of my opponents are paladins, recently joined by murloc quest ones. (i do not record any statistics, the numbers are just guesses)

this week after the nerfs i was lucky to win against one for the first time. but mainly because of lucky draws and unlucky ones for the opponent. against any other decks i can win maybe 40-50% of the time but i rarely see any non-paladin opponents.

currently (2/3 of the month already over and no more star bonus) i’m at silver 10 and i lose every match because all of them are paladins. also i’m suffering even longer because the current quests require even more time to finish.

but my main issue is this: why do i always get those unbeatable opponents? isn’t there an internal mmr system which should give me ones with 10% winrate? or am i the only one losing to them with their constant refilling full board of 10/10s, ursol shooting 30 to face or grunty shooting 10/10s at my minions? since i can’t see their ranks anymore (why?) so they could all be legendary players.

please don’t tell me to just get better or build this specific anti-paladin deck or to just quit the game. tell me if this mmr thing is really working and why does it keep me at 10% winrate in silver 10. also i never give up but instead try to win each match, even the ones i already know that i will lose, so conceding is not part of my losses.
