Can someone help me with my soulsilver team?

Well you definitely have a very good team but with Alakazam I would teach him Focus Blast and get rid of future sight because focus blast can get rid of those dark types he's weak to. I would say Nidoqueen because 1. you have an idea of a moveset you want and 2. if you had snrlax you would have 3 of your pokemon weak to fighting types the other two being lapras and golem. That is what i would do. Hope it helps.
