What are some good Black/White commanders?

My friend has this Black\White life gain deck which revolves around life gain and spending it to use as mana/bringing back stuff from the dead/making things very annoying for opponents using various white enchantments (enchantment which makes it so counters can't be placed on anything,land tax, etc). Can't remember the commanders name though.

I've never really used white before, but seeing his deck made me want to try this combo. I just want it to behave differently though so its not just me trying to copy him
