Bulky Offensive
Power Sakuya @ Gold Hairpin
Ability: Strategist
EVs: 64 HP / 64 FAtk / 2 FDef
Red Mark
-Raid
-Overtake Strike
-Dancing Sword
-Changeling
Basic strategy: Can be brought in on Focus attackers due to the bulky spread and hairpin. The Strategist-boosted Raid is there to deal decent damage on first turn, and possibly breaking any Black Chokers. Overtake Strike is there as your main Steel move, with its priority covering Sakuya's horrible speed, and also being powerboosted by Sakuya's ability. Dancing Sword is your STAB Fighting move. Changeling is there to bring in puppets that cant handle Focus moves very well, since you most likely will be moving last.
Brandish is a possible option, but imo takes away the entire use of the bulky spread.
By using an E- Speed stat, Power Sakuya does have options in Genbu, however this does require another puppet as setter.
