Rest-Talk Parashuffler is quite possibly the scariest thing ive ever seen in NU and should be a whole other set. EVs and Nature are entirely different.
But I have a much better spread for it.

- Dragon Dance
- Sleep Talk
- Dragon Tail
With Toxic Spikes and other hazards (mostly toxic spikes) this set is amazing. Pair it up with a Psychic type to deal with Poison types and spinners that ruin your day and your set. When asleep and with +1 Dragon Dance your stats are
263 HP / 401 Atk / 332 Def / 294 SDef / 363 Spd
