Here are two diffrent Ludicolo strategies that have the same moveset, the diffrence is in the ability. Healing Ludicolo @ Leftovers (Ability= Rain Dish) Rain Dance Giga Drain Surf Ice Beam The idea behind this guy is to keep your Hp up while Fighting. Rain Dance ups Surfs power and activates raindish so you heal and do extra damage. Giga Drain heals and damages using Ludicolo's high SPAttack plus it gets STAB. Ice Beam is just another powerfull attack to work off of his SpAttck. And the Leftovers give a little xtra healing. Speedy Ludicolo @ Kings Rock (Ability= Swift Swim) Rain Dance Giga Drain Surf Ice Beam Speedy Ludicolo uses Raindance to boost his speed and Surfs attack power. with his doubled speed Ludicolo uses brute force to plow through pokemon with the Kings Rock adding flinch. The Flinching and Giga Drain just maintain your Hp a little longer. So, wat do you think. same pokemon, same moveset but the ability makes the diffrence.
