Shadowrun 4th ed. Questions

[a_humble_lich]

As someone who plays a fair bit of Shadowrun, how does one make an "anti spirit wizard"?

As someone who has made an "anti-spirit" wizard that I really want to play, I went with: high astral combat/ mental attributes, the biggest weapon focus you can find, spells like astral armor (preferably with a sustaining focus), and then some other more standard wizard abilities.

Of course that was just the character I made, I don't know what his player did. High banishing might be useful too.

Edit: Apparently I need more Wired Reflexes to deal with the ninjas here.
