Gholdengo

Life Orb Gholdengo is still underplayed for how effective it is, resisting Fairy damage while threatening Floette and Sylveon back with a boosted Make It Rain. Thunderbolt gives it unique coverage the rest of the team doesn't already provide, since between the two Megas there's already enough anti-Charizard pressure without needing Power Gem. Good as Gold blocks status disruption entirely, and Modest with max Special Attack and solid Speed keeps every hit meaningful.
