The idea behind it is to have 3 voltturn users and a mega medicham to blow things back with 'the switch-in to everything' chomp and torn as back bone. I originally had Rotom-W/Thundurus-T instead of Rotom but ground and grass types were bothering me.

Specs Rotom-H is a very fun mon to use, when they think you go for volt-switch you can blow away their lando/exca/amoonguss away with overheat or you can cripple their chansey or whatever other pink blob with trick. The team allows you to play recklessly with medicham as it has healing wish as back-up plan.
