- Thunder Wave
- Encore
- Howl
- Play Rough
A very cool support Pokémon. Thunder Wave slows down faster Pokémon, allowing Scream Tail's team mates to outspeed Pokémon they usually wouldn't. Encore locks an opposing Pokémon into an undesirable move (such as Fake out, Tailwind, a setup move, etc.), potentially rendering them useless until they switch out. Howl gives Scream Tail's ally an attack boost, helping them take KOs more easily and sometimes letting them sweep through teams (Scream Tail itself also gets an attack boost, but unless it accumulates multiple boosts, it won't do much damage). Play Rough is here so Scream Tail doesn't get completely shut down by taunt.
Sitrus Berry provides Scream Tail with instant recovery. Because of the faster pace of double battles compared to singles, this is usually better than the passive recovery given by Leftovers. Tera Steel turns Scream Tail's Steel and Poison weaknesses into a resistance and an immunity in a pinch. Having maximum speed allows Scream Tail to outspeed Iron Moth and unboosted Iron Jugulis, and then cripple them with Thunder Wave.
