Here’s the set I use for Yveltal and it synergies really well with Defog SpDef Boots Ho-Oh. It supports Primal-Groudon and Primal-Kyogre extremely well by eliminating Rayquaza. This Yveltal is built to wall and wear down Physical Attackers, fairing especially well with Physical Rayquaza, Swords Dance Necrozma DM / Ultra, Zacian-C with Tera Steel burned, Marshadow, and Extreme-Killer Arceus.
The Evs maximize Yveltal’s Defensive Bulk, allowing it to easily survive a Stone Edge from +1 Atk P-Groudon and Necrozma-DM. Rocky Helmet allows Yveltal to chip opponents using physical attacks, while rendering Spectral Thief Marshadow’s Sash useless. Tera Steel gives Yveltal a much easier matchup against Zacian-C.
Toxic allows Yveltal to cripple Mons like P-Groudon and non-Rest Kyogre, while Taunt allows Yveltal not to get worn down by stall teams with Salt Cure Garganacl or Toxic Chansey. Roost gives Yveltal reliable recovery, allowing it to carry Rocky Helmet without too much worry. Knock Off allows Yveltal to support the team by removing items, especially Heavy-Duty Boots and Rocky Helmets. Foul Play, combined with Rocky Helmet, is what allows Yveltal to absolutely shut down Physical Attackers. Yveltal absolutely punishes all forms of Sword Dance and Dragon Dance setup, all while being hard to hit back. You CANNOT setup Physically on this without getting absolutely punished.

A well timed Tera is all it takes to survive barely scathed against almost any Physical Attacker, and sometimes it doesn’t even take that. After that, Roost off damage and nothing ever happened.
