Just taken on Chuck, my god what a complete cheese-fest that fight was on both sides. First attempt his Primeape managed to get three critical hit KOs in a row with Rock Slide. Restart.
Second attempt I brought out my level 23 Togepi first, technically should have been suicide, right? Somehow I managed to completely sweep Primeape without even getting hit.
Primeape: Double Team
Togepi: Extrasensory hits
Primeape: Focus Punch charges
Togepi: Extrasensory hits and flinches
Togepi: Quick claw kicks in, Extrasensory hits and flinches again
Chuck uses Hyper Potion
Togepi: Extrasensory hits
Primeape: Focus Punch charges
Togepi: Extrasensory hits and flinches yet again
Togepi: Quick claw again, Extrasensory hits and critical hit KO
For Poliwrath I went to Bellossom, kept using Mega Drain and got it to a slither of hp where he promptly used a Hyper Potion. Got him to a quarter HP again and then he starts sweeping my entire team with 100% accuracy Hypnosis, OHKO Focus Punch and 100% critical hit ratio Surf. In the end I only had Magmar left and chipped him down to 1hp, at which point he used Surf, but Magmar hung on with 3hp left to KO it next turn.
