Answer 1

Gorebyss @ White Herb/Life Orb
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Shell Smash
- Surf / Hydro Pump
- Ice Beam
- Baton Pass / Hidden Power [Grass]

Shell Smash boosts the stats to nice levels, and can be Baton Passed to dangerous sweepers.
Surf is reliable STAB which hits pretty hard after a boost, but Hydro Pump can be used for more power.
Ice Beam hits Grass-types, and gets pretty good coverage alongside Water-type STAB.
Baton Pass is the prefered option in the third slot, as again dangerous sweepers can greatly benefit from it.
If you really don't want to Baton Pass, Hidden Power [Grass] can be used to hit Water-types pretty hard.
White Herb is the prefered item, as it helps especially against priority.
If you want to use Hidden Power [Grass], Life Orb becomes the superior option.
