Snowpoint temple only if you have regirock registeel and regice but to get those you need regigigas in a giveaway its an endless chain unless you go to events
To get Registeel on Pokemon Platinum, you have to have received a Level 100 Regigigas from a giveaway event. Put it in your party, then you go to Iron island B3F.

you have an awesome team but you're using too many legendaries take latios out and put in a electrical Pokemon or a dark Pokemon because you have 3 Pokemon that are legendaries.
