Sableye

Sableye is the team's support backbone, using Prankster to give Rain Dance, Reflect, and Light Screen +1 priority so screens and weather land before opponents can act. Sassy nature with SP invested in HP and SpD gives it the bulk to survive multiple hits and keep setting up. Roseli Berry patches the Fairy-type weakness. Foul Play punishes physical attackers without any Attack investment. It enables the rain core and simultaneously shields the rest of the team from chip damage with dual screens.
