Battlegrounds has sound? I just learned that there’s sound in regular HS. This is mind blowing and i am still not turning on the sound.
“You got this! You’re way ahead!”
Me, as Patchwerk, down to 31 life and technically “ahead”

Unironically the right move.
But my point is that the way Blizzard manipulates is consistent and pervasive… and has nothing to do with losing streaks or frustration. It has everything to do with building players up, over assuring them, and making them think that they are better than they actually are. The losing streak is not the artificial high, the losing streak is the hangover from coming down from the artificial high.
What Schyla says is that if you toss a coin 5 times, and its tails the first 4, this does not increase the odds of the next toincoss to be heads, as the toincoss itself is always 50/50. And this is true.
That there is a small chance to throw 4x tails in the first place has no onfluence on this 50/50.
I believe that, however I also believe that the OP is right, and opponents come in batches. I have observed it enough, kids in the afternoon play other decks than old wallet warriors in the evening. Use the old phrase wallet warrior here to make it more obvious.
If we had insight in the playerbase, the age distribution would differ. I would guess that at lunchbreak you will also have increased winratio as ppl may play a quick game and then and have to throw the game for a number of reasons, just making that one up right now.
Also late at night you will find a lot of drunks playing suboptimal, increasing your winratio.

And I took that personally
If you want to game the algorithm, the most effective way to do that would be to do something called win-trading. It happens all the time in competitive events.
Its not easy to organize, but if done effectively and at a large enough number of competitors you can, to a large degree, game the system to control who gets free wins at what time.
Then a competitive game turns into a cooperative one where you have some binding or non-binding agreement with other players as to who takes the win when.
Another technique that can work well for gaming is called MMR diving. The general idea is tank your MMR to the point where the match making system matches you with very weak opponents. In that time while the MMR is adjusting, depending on the implementation of the MMR system, you can change your behaviour to go full skill mode again and destroy your opponents. If the time it takes for the MMR system to adjust is too long, you can coast to a very high rank beating very weak players. This was a favorite technique of people gaming the arena MMR system in WoW. It also happens all the time in other contexts (such as gambling) and is better known as “hustling” in those.
