Lenora is a new unova gen pool unit that was released a little while ago. I am not sure of her viability as a support, but I can break down her kit.
She has leer which lowers a single targets defense by 1. She has 2 special defense all to raise all allied sync pairs special defense by 2. Her attacking move is facade which does doubled when the opponent is poisoned, paralysed or burned. Her trainer move research time restores the HP of all allied sync pairs by approximately 20% of their maximum HP. Charges the user’s move gauge by 2 for each allied sync pair on the field. When used in a co-op battle, charges the move gauges of all allied players by 2 instead.
Her passives use Status P-Move on Opponent: Special Defense 9: Lowers the target’s Special Defense by 1 stat rank when the user’s pokemon uses a status move targeting that opponent. Debut: Field Special Drain: Applies the Special Damage Reduction field effect to the allied field of play the first time the user enters a battle each battle. Team Pinpoint Entry 2: Raises the accuracy of all allied sync pairs by 2 stat ranks when the user enters a battle.
