Your team is currently pretty weak to sun teams. While Scizor can decently check Venusaur with Bullet Punch you are pretty screwed outside of that and nothing can switch into Venusaur or Volcarona safely so you'll be losing the Weather War most of the time. So something like LO Latias (Timid 72 HP / 244 Spe / 192 SpA) or Dragonite (Rain Mixed Attacker, CB or DD) could work since the both threaten Sun Teams Offensively while being able to take a hit or two from Venusaur or Volcarona (DNite only) even after boosts.
