My late game sweeper, I only bring this guy out when his counters are gone. Sometimes I will use skarm as a lure by switching in skarm on something it resists, then immedietly swap out again to heatran or flygon as my opponent brings out magnazone. The speed ev's allow me to outspeed max base 90 pokes after a boost, including the ever anoying rotom. the rest went into attack (for more power) and defense (to help survive the first hit before breakable armour becomes active)
