How is Regigigas' Slow Start useful? - Answers

Regigigas' Slow Start is actually useless, but you can cancel this ability:In a 2 vs 2 battle, have a Pokemon use Worry Seed on Regigigas.Skill SwapGastro AcidLike Slaking, Regigigas is only useful in 2 vs 2 battles.Simple Beam might be better to use. It's possible that Slow Start is meant to give the opponent a chance considering Regigigas' very high Attack and other stats.I've also read that without the ability in spite of its stats, the stats affected by the ability just remain, meaning Regigigas was meant to definitely be weaker and slower until the ability triggers the change.
