This set doesnt really cripple shedinja too badly as all it usuall does is baton pass out anyway. And Pdon doesnt like losing its choice band since wallbreaking is significantly harder. This set is ok. 6/10.
Also, it might only be me, but i would never switch imposter chansey into Pdon because TA from any set is bound to do serious damage, especially banded sets which are quite common. The threat of TA is too great to switch in.
Anyway guys, I have an imposter Chansey set, but with a twist:
Chansey @ Lucky Punch
Ability: Imposter
EVs: 252 HP / nothing else matters, really
Nature: who cares
-filler
-fillet
-filler
-filler
When Chansey holds lucky punch, her crit rate is increased to a whopping 50% allowing Chansey to easily defeat Quiver Dance PH primal Kyogre, break past things like fur coat (and eviolite i think, could be wrong) and generally make Chansey more powerful.
What do you guys think? This imposter Chansey sacrifices bulk for offensive prowess.
