For me, swapping jewelery was the final trick to play if my teams turned out to be too weak to 3-medal the Winter Rose Garden maps.
As it turned out, I didn't have to use it, even though sometimes a team perished.
In the end, it came down to the RNG nodes and some team reshuffling if the initial attempt failed - and so I managed to 3-medal all the current maps by 2-4 tries.
This was my squad configuration:
Oh, and I needed to keep tabs on the Solar Blast since this time around it actually made quite a difference.

I got lucky and rolled Stewartia from my 10+1 but she is Banana island, on the up side she is another atk nerf girl.

I probably won't be trying the 4- series any time soon for Winter Rose and Bergamot valley - teams are at about 40k each and the maps I've run I tend to lose squads. Blossom Hill and Lilywood are more likely to get there as my teams are substantially stronger, Banana Island is somewhere in between. I'll be working on slowly leveling up girls from the weaker islands to help but it probably won't be quick.
