[SET COMMENTS]
<p>This Smeargle set surprises most opponents that expect it to be Baton Passing things like Belly Drum, Substitute and Ingrain. This Smeargle is designed to mess up the opponent's team as much as possible, hindering them with Choice Scarf and sleeping them with Spore.</p>
<p>The set is intended to be a lead, to start messing with the foe's team as early as possible. First, Trick your Choice Scarf onto either something slow like Bronzong and then you can attempt to Spore the switch-in. Smeargle should be saved for later to hopefully take out a slower sweeper or tank with Destiny Bond or Explosion. The last slot can be one of many viable options. U-turn scouts out the opponent's sleep absorber and is generally useful for scouting while Haze can also help Smeargle save the team from a Garchomp with too many Swords Dances, Smeargle still has its Scarf.
COMMENTS: Unsure about other options, because let's face it: there are many of them. Smeargle suffers most from four-moveslot syndrome, and things that might be useful include: Taunt, Encore, Stealth Rock, Toxic Spikes, and Memento. Each have their merits, and could fit in either of the last two (or even three) slots.
