OK, Create your build ^^.Ah, so not 62 hitpoints, but 57. Better and better.
Tactic is simple -- targeted 9th level dispel magic -- no death ward, 26 hitpoints, no warding bond (wait you forgot that one for your Sim!), no Aid. You get to keep the 24 temp from Leadership. If you suggest counterspell, well, that's going to be tough because I took metamagic adept (distant spell) and cast it from 120' away.
Several Wizards have already died, will it be one more?
