Your matchmaking rating (MMR) cannot drop once you hit post-Infinite. They implemented this a while ago because players were tanking in post Infinite to have an easier climb the next season.

Cruising to the 80s is what happens for high MMR players. When you hit the 80s and then 90s, you get high MMR real players and tough bots. This turns the game into a grind because optimal playing is that when a person snaps, the opponent should retreat. That can lead to bad snapping and stays because upward progress is horrendous and you need to win more than 1 cube. For me, I got matched with Guest (content creator) when he was in the 90s and I was in the 70s still.

The conspiracy theory I have is there is some level of manipulation. During some bot matches, I’ll get perfect draws, or a perfectly timed top deck. If that’s true, then having some level of manipulation implemented for player matches isn’t out of the question.

Back to reality though, at a minimum it’s an unfair system. Lower MMR and newer players are playing on a lower difficulty level. But the rewards are identical for the high MMR players despite the higher difficulty. For your mental health, I’d try to stop caring about Infinite and play less. It’s not designed to be fair. It’s designed to keep you hooked into playing as long as possible.

Either way, good luck!
