In my opinion you should consider changing Electivire (which is not as good as it looks actually ] , for anything else immune to ground, such as Thundurus(can be mixed or the Nasty Plot set) or an Eelektross (Assault Vest) or just bulky overall so it can switch on Excadrill when Zapdos gets too weak.
If you hate Choice teams that much, I have tested a pretty cool Magnezone set. that can get rid of Excadrill (which is the one of the biggest threads for a mono electric), you'll use a Balloon Magnezone, but you have to be careful and make sure the foe's Excadrill will use Earthquake, then you use Magnet Rise, and start spamming HP Fire, it does a pretty decent job. Try it if you want to. And if not, change yours ability to Magnet Pull anyway.
