Question

Because zap cannon has low accuracy

Answer 1

I think you should keep thunderbolt because like you said zap cannon has very poor accuracy but it does do a lot of damage. Thunderbolt has amazing accuarcy and can deal a good amount of damage so I think you should stick with thunderbolt. Thunderbolt also has a 10 percent chance of paralyzing the target so in that case you should keep thunderbolt.

Hope I helped!~awesomebanana917

If you are wanting you Eeleketross to be a haxy Pokemon then go for Zap Cannon but remember it is not very accurate...At all.
If you just want a good Special sweeper than Thunderbolt is for you. Personally I would go for Thunderbolt but it completely depends on what role you want your Eeleketross to hold and maintain.
Hope this helps! ^.^
