You people are crazy. Marveni is totally a blood nation (when played right).

Blood + Death on pretender + blood multihero + vampire lord summons/Heliophagi/etc. (And Marveni's multihero always finds like 15 slaves when he searches, so he's a really good bloodhunter).

And yes, Marveni will get its pick of unique blood summons, because chances are it will out-research anyone else if it pushes blood.
