I charged throgh route 23 and Victory Road using only my Blaziken ane Chandelure because I can't be bothered training my other 6 pokemon.
I attempted to beat the E4 without any extra training. I was swept by Grimsley's Krookodile's Earthquake.
So naturally, I did what any other sane person would do. I tried again. This time I left Grimsley to last. I beat Mashal with Blaziken and I beat Caitlin and Shauntal with Chandelure. I tried again against Grimsley and my Blaziken just managed to survive the Earthquake and swept the rest of his team.
Then comes Iris. I KO Hydreigon and Aggron with Sky Uppercut. Then Haxorus comes in, Dragon Dances, and OHKOs everyone with Earthquake -_- (why does this sound familiar)
I still can't be bothered training, so I'm just going to continue battling against the E4 and Champion until I win.
