Hisuian Electrode

The first Pokemon introduced into Pokemon Go from the game Legends Arceus, Hisuian Electrode sports a relatively unique Electric/Grass typing. Unfortunately its stats are almost identical to that of Kantonian Electrode, which isn't very impressive for the PvE meta. However its PvP performance is much more interesting. 

Best PvE Offensive Moveset

• Thunder Shock gets STAB and outperforms Hisuian Voltorb's other Fast Move option.
• Don't use Tackle. 
• Wild Charge pairs well with Hisuian Electrode's role and Fast Move.
• Energy Ball is not an impressive move despite having STAB here. 
• Swift is even worse. 

Best PvE Defensive Moveset

• Thunder Shock deals pitiful damage on defense, even with STAB.
• Tackle is less likely to be resisted, but against a neutral attacker the lack of STAB is even worse. 
• Wild Charge performs well on defense, though it's easily walled by Ground-type attackers.
• Energy Ball might catch Ground-type attackers by surprise, but its slow animation makes it easy to dodge.
• Swift is terrible. 

Thunder Shock benefits from STAB and generates energy very quickly, letting Hisuian Electrode use its strong Charge Moves sooner.

Wild Charge can threaten massive damage, especially when stacked to 90 energy, but can be difficult to use with its harsh self-debuff. Energy Ball provides useful coverage against Ground-type Pokemon that doubly resist Electric moves, but its higher energy cost leaves more to be desired. Swift is terrible.
