After 30k trophies..

I'm a pretty casual player, and I finally hit 30,000 trophies. Well, the game (at least in my opinion) became significantly harder, for example, I can't seem to get past the first two levels in solos. When playing against others, luck varies too much, you might come across someone with a Jelly SE or even a Golden Broom, and the latter can easily defeat me. At least it's good that you get a box every 3 hours, but where do you get the money for SE boosters if you can't win?"
