Soul Silver team needs work.

[Phliilps616]

I have a few Pokemon I know.

Victreebel
Lanturn
Typholsion or other fire
Tauros

But I have questions on last few. When should one evolve Murkrow and Mamoswine, what level? Or Victreebel? How do I hear about Mawile swarm, it won't show up? Would you recommend Cloyster/Walrein instead of Lanturn?

Please give all thoughts! Much thanks!
