Doing A Hardcore Nuzlocke of Pokémon Black Is...An Experience
I didn't stop at Ghetsis; I took on the post-game as well. That means battling Cheren, the Elite Four, Alder, the Bianca rematch, GAME FREAK's Morimoto, and Cynthia (and if you really want to punish yourself, mandate the battles against Veterans Shaun and Julia).
Some general tips for the public; you have no idea how goated Substitute is. Excadrill used it alongside Swords Dance to sweep N and Ghetsis; Volcarona did the same with Quiver Dance to end Caitlin, Marshall, and Alder; Haxorus combined it with Dragon Dance to take a bite out of Cynthia
P.S. that Volcarona came from an Egg I got on Route 18 and hatched on Skyarrow Bridge, not the one in Relic Castle's depths. In case the Yamask confused anyone. She was loyal and powerful...right up until Spiritomb came back as Cynthia's last Pokemon and used Sucker Punch on her
