I agree with Essence that this card is too much of an investement to put into 1 of your own creatures considering the fact that first of all, just increasing a creature's health by large amounts doesn't make it invulnerable (e.g. fallen elfs, rewind, freeze, etc.). Also, you'll be putting that creature out for 6 turns, which drastically decreases the value of that creature simply because it is out of the action for so long. In other words, using BB on your creatures and waiting for 6 turns is just not a good enough strategy, alot can happen in 6 turns.
However, combining adrenaline with BB and possibly Otyugh does sound like a good idea, and also using BB with a damage absorbance creature (e.g. armagio). But these are rigid and specific combinations that might require a specialized deck.
So overall it seems that Basilisk's Blood will be more useful to us as a creature control card considering its high stasis time.
