This is Shuppet's best attempt at a set. Shuppet's poor Speed means it can take advantage of Trick Room while supporting its teammates in the process. Destiny Bond can be used following Trick Room and has the potential to ensure at least one KO before Shuppet goes down. Taunt is listed as it blocks any opponent's attempt to set up on Shuppet and forces the opponent to attack, which in turn, guarantees a KO with Destiny Bond. In the final slot, Shadow Sneak is used for STAB, but Sucker Punch has a higher Base Power. The main benefit to using Shadow Sneak over Sucker Punch is that it still hits even if the opponent doesn't attack Shuppet. It should be noted, however, that, if Shadow Sneak is used, Shuppet is completely walled by Normal-types.
This set only needs to invest in Attack because Shuppet is designed to be as frail as possible. If you decide you don't want to use Shuppet as a lead, you can invest in HP and use Eviolite instead of Focus Sash for survivability. If you're looking for a defensive Trick Room user though, Yamask is generally a better choice. Will-O-Wisp can be used over Taunt if you wish to cripple physical attackers, though this carries the risk of allowing Pokemon such as Dwebble to setup on Shuppet.
Pokemon that can take advantage of Trick Room are ideal partners, especially those with high offensive stats. Trapinch is an excellent example, as it has base 100 Attack, powerful STAB moves, and Arena Trap, which means the opponent is forced to take a hit. Omanyte and Solosis are specially based sweepers, and both of them have decent defensive stats and good type coverage. Other examples of good partners include Cranidos, Darumaka, and Magnemite.
Due to Shuppet's frailty, most priority moves will KO it prematurely. Sucker Punch, Ice Shard, and Aqua Jet are the most troublesome, as they are common on powerful attackers such as Croagunk, Snorunt, and Buizel. A Steel-type such as Bronzor makes an excellent teammate, as it can switch into most common priority moves with ease and use this time to set up entry hazards, stat boosts, or even dual screens. Magnemite is a more offensive option if you require more attacking power, but the added support is always beneficial. Finally, Dark- and Fighting-types can get rid of opposing Ghost- and Dark-types. Pawniard can destroy most Ghost- and Dark-types with Night Slash and Brick Break, and Sandile can act as a revenge killer with a Choice Scarf.
