Blood's a little moot unless you stack its land with blood-income sites. Pop loss + utter lack of early blood mages (neither Dusk Elders nor Spectators get it, IIRC)= no blood income to speak of. The Lord of Corruption spawns blood slaves, but he's only one guy and doesn't spawn THAT many.

If you wanted to ensure that a mobile pretender was unlikely to kill itself easily, the Armor of Virtue would help.

Sphinx with high Death, high Astral, full slots to avoid curse/horror mark (a Skull Mentor, a Ring of Sorcery, maybe a Spell Focus, can't remember if it gets a fourth or even a third slot).

Accompany with Bowl of the Lost for free Banes if we're being cruel.
