BPhillipYork: This is nice for swinging your commander through if it absolutely has to deal combat damage for a trigger or something like that
There are tons of ways to combo using Protean Hulks death trigger, some of which are a bit convoluted but still get the job done
The immediate benefit, however, is that you have access to White's unparalleled removal spells, especially enchantment removal that traditional Red/Black Vampire decks can't easily deal with
Likewise, Sindbad is another card thats on color, and has synergy with the rest of the strategy, but is somewhat inefficient for what it does, and makes all of the cheap removal in the opponents deck (such as Chain Lightning) more relevant
Strategic Betrayal Edicts are always shaky because your opponent chooses which creature to remove, which gives them an uncomfortable amount of control over what lives and what dies
