Lanturn (M) @ Salac Berry
Trait: Volt Absorb
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Thunder Wave
- Surf/ Whirlpool
- Electro Ball
- Confuse Ray/ Ice Beam/ Signal Beam
First, If you chose Whirlpool, you use that to trap the opponent. Surf is just a strong STAB move.
Thunder Wave is to slow the opponent down, powering up your Electro Ball.
Confuse Ray is for possible free turns of damage.
Ice Beam & Signal Beam are coverage.
Salac Berry is for extra speed
NOTE: I did not put Scald as an option because you do not want to risk burning them instead of paralyzing them. You need to paralyze them for Electro Ball's sake.
