Pokémon Y Nuzlocke Challenge: In which the playthrough gets very difficult

Up until this, the fourth installment of my Nuzlocke run through Pokémon Y, my adventure had been fairly smooth sailing (one unfortunately KO’ed Flabebe notwithstanding). But I seem to have reached the point in the game where enemy Pokémon take off the kid gloves, and stop pulling their punches. If this is what the rest of the game is going to be like, I may be in over my head.
