Mega Meganium

Mega Soul activates Sun-like effects. Solar Blade charges in a single turn, and Synthesis heals for two-thirds HP instead of half. Solar Blade is 150 BP Grass STAB firing instantly under Mega Soul. Rain from Pelipper halves Fire damage, removing Meganium's primary weakness and creating a unique environment where instant Solar Blade and Fire resistance coexist simultaneously. Dazzling Gleam provides spread Fairy coverage. Calm nature maxed Special Defense with HP and Special Attack investment creates a durable special attacker. Synthesis sustains across a long game. The Rain and Mega Soul combination makes Meganium unexpectedly durable in a weather team.
