This is not a real thing. Your opponents aren't playing 5d chess predicting what you'll play and counter queuing you. This just variance combined with confirmation bias.
Like the other guy said, it's better to just play one deck and stick to it. Not only because you can't predict the ladder, but also because learning to play one deck well will get you farther than playing an assortment.
You can play all the games in the world but bad draw game after bad draw games after opponent having the opening hand nuts will make you reconsider your choice.

I can relate.
Hard to stick to one deck when you hit a wall of losses. The win/loss swings in this game are the worst I’ve ever seen in anything gaming.
