Foul Play makes Yveltal an excellent revenge killer against many offensive teams, being able to use the Attack boosts of Pokemon such as Swords Dance Arceus formes, Primal Groudon, and Necrozma-DM against them to break right through them before they have the chance to cause major damage. Dark Pulse is a consistent and strong Dark-type STAB move if a more consistent damage output is required.
* Oblivion Wing allows Yveltal to reliably revenge kill Marshadow and maintain its health somewhat. Roost may be used to keep itself healthy as well, but locking into it can be risky against many teams.
* Defog allows Yveltal to be one of the best solutions to hyper offense teams in the tier, clearing entry hazards extremely early due to how many switches it forces with Foul Play, notably not having its Speed dropped by Sticky Web. If its team already has a Defogger, Toxic may be chosen to punish support Arceus formes more consistently.
* U-turn allows Yveltal to better take advantage of Pokemon that switch in like defensive Eternatus, Arceus-Dark, and Arceus-Fairy to maintain momentum for its team.
* The given EV spread allows Yveltal to outspeed fully invested base 95s such as Rayquaza or Kyurem-B and live a boosted Outrage from Dragon Dance Ultra Necrozma, allowing it to revenge(rh) kill with either Foul Play or Dark Pulse with the rest being dumped into Special Attack to strengthen Oblivion Wing.
* Tera Dark allows Yveltal to OHKO +3 Zacian-C with Foul Play and removes its Stealth Rock weakness; however, Tera Steel is also a good option to allow Yveltal to become much more resilient against the likes of Extreme Killer Arceus while also turning its Stealth Rock and Fairy-type weaknesses into resistances.
* Because Yveltal is still quite bulky and is able to punish foes even if they boost, it is best to use Yveltal proactively rather than reactively to keep setup sweepers in check by bringing it in on predicted setup moves or to take a hit and fire back with Foul Play.
* Yveltal fits very well on offensive teams where its short-term utility and late-game cleaning prowess are put on full display, being able to almost singlehandedly shut down entire hyper-offense teams that such structures otherwise have trouble against, and trade blows with surprise sweepers that may otherwise run away with the game.
* Alternative Defoggers like Arceus-Ground or Giratina-O are great teammates on such teams, matching up very well against the tier's best Stealth Rock setters and keeping hazards off for Yveltal to stay as healthy as possible throughout a game.
* Offensive Necrozma-DM and Primal Groudon variants are also notable partners, being able to take advantage of the many switches Yveltal forces and the common Fairy-types Yveltal will find itself luring in for a safe setup opportunity, allowing Yveltal to clean up later. Furthermore, they are capable of setting up Stealth Rock in order to further facilitate Yveltal in the late-game, as Yveltal greatly appreciates the prior damage on foes such as support Arceus formes and Eternatus to more easily clean up games.
