What are the best routes or areas to level a karp to 90 plus.?

Cerulean Cave, Mt. Silver, Dragon's Den.

 

Not sure how others level their karps. I level-up mine by this:

 

*Make sure karp has tackle*

 

*Get a (party lead)false swiper that could manage to cripple -- e.g., 1hp & paralyze, the enemy pokemon(high level recommended for bigger xp)*

 

*Let the false swiper die against the enemy pokemon*

 

*Enter the Karp, and steal the kill*

 

**Make sure Karp is the one who'll attack first. If not, use a focus sash**

 

How about letting magikarp down to 1 HP and use flail it learns on level 30. It then has a base attack of 200 which should be able to one shot a lot of Pokemon.

 

After all, the only thing that Magikarp can is being fast so it will outspeed the enemy fairly quickly on higher levels.

 

 

Has anyone tried the flail strategy?
