Though to be fair this defeat was expected that he would be hammered even after defeating paul.

just didnt think the defeat would be this severe? Maybe the writers should of let Ash use all his strongest pokemon ??

Sceptile
Charizard
Infernape ( if not too injured?)
Torterra
Snorlax
Pikachu

Even if its not much varied in types go for brute power might of lasted longer will never know.
