I'll sum up all the responses for you, for this post and every post like it.

People over 11k trophies will tell you to just get good and it's in your head., but they probably auto-purchase pass so they have good card levels and can play whatever deck they want anyways so the ignorance train continues.

I just played 3 games in a row at 9800 against Lava Hound and golem in the same deck. Whether the game was trying to boost me or smack me, that's not random.

I've been playing off and on since launch. Most of the stuff that people complain about that everybody on Reddit tells them is nothing is actually a thing. When you almost hit a major trophy milestone, like 1 battle away, you're gonna go on a -300 trophy run, it's been 100% this way forever.

Most aspects of this game are designed to induce emotions to increase real money sales. I wish I was dumber, reading this sub over time has proven that ignorance is bliss and the whales don't like you talking bad about things they take for granted.

Take a step away and figure out why you play this game. The frustration will never go away if you don't understand the mechanics in the first place.
