So Asmo has some problems but the main one us requiring to draw 7 / lose 7. This deck is not going to make BBBB ever, it needs to make and then and .
Jin refuels me 7 for no mana if I make it to my endstep, and CSphinx refuels me 6 if it survives a turn, neither at any life loss.
It's somewhat problematic about Vilis, Broker of Blood too, except that he triggers off of life loss that I was going to suffer anyway and kinda deters people from attacking since non-lethal attacks are going to refill my hand.
