I'll bring this to the table:
Screech and Acid Spray and a contrary Shuckle creates the tank of tanks,which is effectively immune to everything bar status problems and set damage attacks-but rest and wake-up slap could help solve that problem.
This could pair up to make an amazing sandstorm team-Tyranitar could use screech but you could use something faster for reassurance.
Quagsire is the only pokemon that can use acid spray & additionally will be unaffected by sandstorms.
But I play triple battles majorly, so I don't see much benefit outside of this style-Tentacruel could be a fine partner for doubles, since it has both of these moves in its movepool.
