Gothitelle

Gothitelle excels as a Trick Room setter in Battle Spot Doubles thanks to its great ability, Shadow Tag, which prevents your opponent from switching Pokemon and can lock them into bad match-ups. Gothitelle has a good support movepool with useful moves to aid its teammates, such as Heal Pulse and Helping Hand. Thanks to Shadow Tag, teammates with Intimidate can repeatedly switch in and render trapped physical attackers useless with the multiple Attack drops. However, as a Trick Room setter Gothitelle doesn't offer much more past its ability; furthermore, it's not nearly as bulky as other setters and doesn't have a unique typing either.
