As far as I can find, the only moves that do that are Tail Glow and Cotton Guard.
- Tail Glow: Raises Special Attack by 3 stages
- Cotton Guard: Raises Defense by 3 stages
Quiver Dance, Shift Gear, Shell Smash, and Coil don't raise one stat, but raises different stats at once.
Belly Drum maxes your attack
Momento lowers your opponets attack but you faint in the process
