SmashPass Smeargle is one of the best pokes to use in an offensive team.
You have 2-3 offensive pokes so depending on the opponent's team,make your pick and then go to town!
Just make sure you clear the hazrads from your side and that any sashes and Sturdy abilites are broken(except if you want to pass to Zekrom or Reshiram which don't care about Sturdy users)!
