Bad luck so far

So my card drops have been less than stellar and I have 600 bucks. The enemies are now Hard. I'm getting my ass handed to me boys.
Since losing gives me boosters, should I just keep losing until I dont suck anymore? Is there a way to go back to some easier enemies? The other worlds I've tried are also hard.
Advice appreciated. I'll be losing for the win until then.
