Took nearly an hour but I finally beat her. Shelly is no doubt one of the hardest leaders in Reborn period.  Illumise's  rain dances are extremely annoying as anortih, easily shelly's most dangerous pokemon aside from yanmega, gets swift swim off it and becomes near impossible to outspeed at this point of the game unless you're packing a SSer of your own.  Turns out my key to winning was leading with roselia and cherrim, having roselia set up a growth to take advantage of the field boost, and cherrim to use sunny day to cancel out illumise' rain. This also creates a rainbow field which is key, as nature power becomes a buffed aurora beam and with +1(as masquierain leads with struggle bug) roselia can OHKO both masquerain AND Yanmega(she can survive at least one air cutter, even a critical from full health). lso cherrim improves special defense while in sunny mode which is pretty nice, I'm surprised at how useful he's been so far.  Keeping the rain off the field makes anortih so much more manageable, and illumise will keep spamming rain dance so long as you keep changing the weather unless one of your mons is in critical health which causes her to use struggle bug. Anorith outside rain is slow and gets one shot by roselia's giga drain. Araquanid looks tough but isn't really, a strong physical attacker can cut him down pretty easy, I used leavanny. For the fireflies I had jumpluff clean up via acrobatics.  Easily one of the hardest fights thus far,  but if you play your fields correctly and keep freakin anorith out the rain it's a winnable fight. 

Was roselia always this beastly? I used to think it was a novelty mon back in the day (pre gen 4) but it's an early game hero and MVP so far. It's easily the best grass/poison type early game.

Also I have a leaf stone now, but who to use it on? Gloom, pansage, or should I save it for nuzleaf? I think I'll go with the last...
