Swords Dance augments Attack. Precipice Blades is a powerful STAB for Arceus-Dark and kind. Crunch, with Tera Dark and a boosting item, annihilates Giratina-Origin from full health. Fling, through TR43, assassinates both Giratina-Origin without Terastal and Giratina with Tera Stellar. This is also functional with Earth Plate and Tera Stellar after Stealth Rock. Tera Blast, through Tera Fairy and a boosting item, destroys Zygarde and Giratina-Oirgin as it additionally enables an advantageous matchup against Foul Play Yveltal--lacking the Fairy- and Fighting- weakness of Tera Dark. Natural Gift, beside Ganlon Berry, confers an Ice-type assault for Giratina-Origin and Zygarde--the former loathing one elevated by Tera Stellar. Rock Polish is in league with Rockium Z, hastening Groudon for a sweep. Stone Edge marks Flying types; Rock Tomb performs selfsame but lowers Speed.
Life Orb bolsters all moves; Earth Plate confers power to Precipice Blades only in exchange for absence of recoil; Focus Sash fashions Groudon into a panacea; Expert Belt quietly increases the sting of moves effective to the opponent; Lum Berry eases setup against Giratina-Origin, Glare Zyagrde, Sacred Fire Ho-Oh, and Will-O-Wisp Arceus forms; Rocky Helmet punishes Zacian-Crowned for an ally Heat Wave Yveltal; Heavy-Duty Boots ignores Sticky Web--advantageous if the foe is a Sticky Web team themselves; Rockium Z, through Stone Edge and 248 Attack alongside an Adamant Nature, eviscerates Giratina-Origin following Stealth Rock damage and a serviceable chance to kill Tera Grass Ho-Oh unchipped.
