Yah that fight is super hard so no worries if you're stuck.

Who is your buddy (Florinia or Julia) in that fight?

Golem worked well, for me. My set on it is: Bulldoze, Earthquake, Stealth Rock, Stone Edge and i alternate quick claw and scope lens (for moves accuracy), on it.

 

You want an average to good speed, hard hitting plant pokemon, i believe... Helps against Blake, plays its part against Solaris and Orderly John, as well... In old times i had my Cacturne, this time a nice Exeggutor.

 

This fight seems to be easier in episode 18, in comparison to episode 16, or something. Like a number of other fights, before it. If you had a hard time and hit a dead end, use a Strength Glitch, to return in Reborn City through Route 1 and go breed yourself 5 correct IV team.
