Description: This tentacruel is best set for Rain teams! Scald is an obvious, decently strong STAB move that has a high chance to burn, which is always good. Protect is so you can stall out the Black Sludge+Rain Dish recovery method is AMAZING. Toxic Spikes is just a useful hazard that is uncommon on most Pokemon in the OU tier.
Options: Rapid Spin is always an useful, exclusive move that removes all hazards out of the playing field for it's trainer and fellow team members.
