I see electrode being of more value to me than Persion.
1. Electrode out-speeds every UU and NU Pokemon.
2. With Focus Sash, I can easily set up a Taunt, and then at LEAST Rain Dance before dieing.
- Electrode's speed is very important for using Taunt. If you led with your Persion, I would hit you with Taunt first, making your Taunt, Hypnosis, and Rain Dance pointless.
3. Explosion.
- This move speaks for itself, if I end up getting Focus Sash's 1HP survival after I successfully Taunt and Rain Dance, well there's not going to be much use for him anymore, so why not finish it off with a big bang?
4. Thunder.
- This move will more often than not go unused, but it gets an added accuracy boost in the Rain, and will take down Crobat and Charizard leads.
5. Soundproof.
- For some stupid reason, Smogon decided to put Yanmega in the UU tier. Electrode is one of the best counters for Yanmega because of it's Soundproof, and super speed stat.
