Yeah cases are basically gambling. I learned to just buy what I want directly instead of hoping for luck. Been looking at knives lately since they keep their value better than regular skins. Navaja knives are pretty affordable compared to other options and still look decent in game. The market has tons of different patterns and wear levels so you can find something that fits your budget. You can read here about different navaja options if you're interested. Way better than spending the same money on cases and getting nothing good
