Why I built this (and what I found out about my own gameplay)

I was stuck at 15k trophies for weeks and couldn't figure out why.

Kept blaming the matchmaking. Kept thinking one card was the problem.

When I actually ran my own battle log through the AI the first time it told me I was playing a Cycle deck like a Beatdown player. Waiting to build big pushes instead of just cycling fast.

Obvious in hindsight. Completely invisible when you're in the middle of a losing streak.

What's the most surprising thing you've learned about your own playstyle?
