Tentacool @ Leftovers / Eviolite
Ability: Clear Body
EVs: 160 Atk / 76 Def / 36 SpD / 196 Spe
- Rapid Spin
- Toxic Spikes
- Knock Off
- Acid Armor / Protect
Use this as a lead. Rapid Spin clears hazards, and Toxic Spikes can be good to bad Poison opponents on switching. Give some Pokemon Protect and it can be quite good! Knock off to stop opponent's leads. Acid Armour boosts Defense wich can let you live a couple of moves, especially you don't want to take an Earthquake to the face. Protect is stall with Toxic Spikes, or scouting to see who to switch into, and get a better look at the opponent's moveset.
Hope I helped, have fun using this set!
