>>45478417If you're running a Nasty Plot/WoW set on Spectrier, I recommend substitute instead of Mud Shot. You probably don't even need Nasty Plot, though. The reason being that Spectrier hits hard enough already, and none of the Normal/Dark types that wall Spectrier already fear non-STAB Mud Shot that's not super effective. If you go for Sub set, you want Leftovers to continuously set substitutes. Substitutes are valuable protection against Pokemon that would normally kill you with priority, like Rillaboom or Barraskewda, allowing Spectrier to wreck havoc for a much longer time.
Urshifu should be running Iron Head or Poison Jab in place of Thunder Punch. Either of them will help it not be bait for Fairy types. Poison Jab is generally considered better because Urshifu doesn't have any problems hitting Ice or Rock types for SE damage, and the poison chance + hitting Tapu Koko and Tapu Fini for SE damage is superior.
>4th move on ElekiExplosion, Thunder (if you're running rain), Rising Voltage (if you're running terrain), or Thunderbolt. Electro Ball isn't very good as a main STAB, since it'll be 60 base power against anything with over 90 base speed (Urshifus, genies, Moltres, Zapdos, Barraskewda, Cinderace, scarfers, etc)
