Aegislash

Weakness Policy activates on a super-effective hit, granting +2 Attack AND +2 Special Attack simultaneously. In Blade forme, both stats immediately reach devastating levels. Stance Change shifts between defensive Shield forme and offensive Blade forme based on move selection. King's Shield blocks most moves and drops the attacker's Attack on contact, punishing physical attackers for targeting Aegislash. Flash Cannon hits Fairy types super-effectively as the dedicated counter. Shadow Ball provides Ghost STAB coverage. Shadow Sneak gives Ghost priority for finishing weakened targets. Quiet lowers Speed. Acting late in the turn, the Weakness Policy payoff matters more than Speed in this configuration.
