Jellicent should be Bold and have this EV spread: 248 HP/212 Def/44 Spe. Also, it needs Recover over Substitute to stay around longer and Substitute shortens the time it has on the field if it lacks recovery
Give Darmanitan U-turn over Earthquake or Superpower as a scouting move
Since Scizor is using a bulky SD set from the looks of things, I'd use 252 HP/40 Atk/216 SDef. That way, it can hits more easily.
