I need some tips on how to beat Fresh Start challenge.

First of all is it even worth the effort? Does it give a voucher if you beat it for the first time or is it just for brag. Honestly I think it would warrant a Golden voucher considering...

I've tried a couple of times and lost at 25 or so

My team was Poplio, Fuecoco and the grass cat(forgot the name) Firt time I got hit by double electric battle and my team got fully paralyz and died.

Second time I lost because Fuecoco died and my "carry" was weak to rival Grovyle.

What does I do besides picking best starters? Prioritise lures and hope I don't get another bad freaking doubles? Without egg moves the starters hit like a wet noodle and it feels so slow (Ps: I can't beleive someone was adding modifiers on top of this challenge ge like how do you bear this insanity ma man?)
