Timid Nature
- Thunderbolt
- Volt Switch
- Electroweb
- Protect

Overview: 

Regieleki's astounding Speed and powerful Electric-type moves fueled by Transistor, along with it providing speed control with Electroweb, make it an excellent speedy attacker. Transistor allows Regieleki to hit deceptively hard and greatly threaten Pokemon like Kyogre and Tornadus. Thunderbolt 2HKOes Zacian-C and Urshifu-S, along with OHKOing any Urshifu-R without Focus Sash. Volt Switch is weaker than Thunderbolt, but it allows Regieleki to quickly switch out of disadvantageous situations and take advantage of opposing switches while still dealing damage, and it synergizes well with other pivoting Pokemon like Rillaboom and Incineroar. Electroweb is especially useful when considering Regieleki's great Speed, which allows it to lower the Speed of Pokemon like Calyrex-S before they can even move. Focus Sash circumvents Regieleki's poor bulk, and Protect allows it to preserve that Focus Sash. Regieleki is useless against Ground-types such as Landorus, so Pokemon that can handle them relatively well like Urshifu-R, Rillaboom, and Kyogre make great partners for it. Pokemon that appreciate it's speed control like Groudon are also good teammates, especially because Regieleki handles Kyogre for Groudon quite well. Regieleki's great Speed and offensive utility make it beneficial to almost any team archetype in the metagame.
