Ok this is coming from a Life wizard 1. I would say 38 because you would have shatter. 2.After tower shield i would recomend sun spells and star spells but you have to be fifty. So train death or life so that spirit blade helps the spell be stronger and try to get your hands on mastery amulets. 2a.Of couse always train tower shield but dont train higer than tower shield 3.I also like damage boost to but resist is also helpful 4.If you could i would try for both of them( I know it is possible because my friend has both) 5.Lots of blades,AOE spells, minions,Attack spells,Time of Legend,and shield and what you deen worthy to be in your deck. But you should try to ask a magnus or master.
