Would having someone damaged by sand (like Hydregion) not be a bad idea in a sand team? Would I not be shooting myself in the foot, in a sense?
Sorry if that is a dumb question.
not really, if you make a sand team with all sand resistors, rain and sun would destroy you
the standard sand team is ttar-landorus i-keldeo-rotom wash-celebi-jirachi iirc, only half take no damage from sandstorm. Its just how well it supports the team
