Regieleki offers Electric teams an incredibly fast cleaner and pivot, shocking threats such as Iron Valiant, Spectrier, and Greninja. Volt Switch lets Regieleki punish foes like Amoonguss, Galarian Slowking, and Hisuian Goodra, which can take advantage of it, allowing teammates like Zapdos and Iron Hands to exploit them instead. Rapid Spin leverages Regieleki's capability to force opponents to bring in a Ground-type or risk significant damage, providing Electric teams with much-needed entry hazard control. Thunder Wave mitigates the threat of Hisuian Lilligant, Spectrier, and Zamazenta if Regieleki is unable to finish these off. Heavy-Duty Boots enhances Regieleki's ability to pivot and consistently remove entry hazards. Alternatively, 28 Atk EVs in conjunction with a Naive nature could be considered, and Magnet is recommended when using Regieleki with Wild Charge to secure an OHKO against Flutter Mane. Magnet also enables Regieleki to reach specific damage thresholds, such as OHKOing Iron Valiant with Thunderbolt. A Timid or Naive nature with maximum Speed EVs is needed to outspeed Choice Scarf users like Iron Valiant, Enamorus, and Hisuian Zoroark.

Given that Ground-types like Ting-Lu, Great Tusk, and Quagsire shut down Regieleki's antics, teammates like Nasty Plot Rotom-W, Swords Dance Iron Hands, and Substitute Zapdos that capitalize on these are crucial for its success. It's important to keep in mind that the player using Regieleki can also choose to double out when anticipating a Ground-type switch-in, allowing teammates to threaten these walls. In return, Regieleki eliminates Greninja, Iron Valiant, and Chien-Pao, which threaten its allies. Magnezone can equip an Assault Vest to check Choice Scarf users like Flutter Mane and Greninja, which zoom past Regieleki, and it can wear down Landorus-T and Quagsire as they repeatedly switch in. Sandy Shocks provides entry hazards to further wear down the opposing team, is bulky enough to bear a hit from and deal with Choice Scarf Sneasler, and puts pressure on Quagsire and Glimmora. Pawmot handles fast Ground-types like Landorus, applies pressure on Flying and Water teams with its Ice- and Grass-type coverage, and grants Regieleki a second chance at sweeping through Revival Blessing. Thundurus-T and Rotom-C are also appreciated, as Thundurus-T provides colorful coverage to deal with Poison- and Ground-types like Amoonguss and Great Tusk, while Rotom-C is able to greatly threaten the entirety of Water teams with its STAB moves.
