Suggesting to me that you're using this deck for ELO, Bloodh may seems to be better equipped as it can create a huge life gap.
However, Lizbeth is much more solid in my perspective. With piranas' bonus, hardly will you be able to face yourself against 2 SOA and therefore, you can actually avoid to have your Lizbeth to be against that annoying piece of dirt.
That being said, why do I not recommend Selma for the extra pills that you can gain when victorious? It's very simple, as I mentioned above that Lizbeth is much more solid, she can actually take down much more cards which Selma might have a problem facing, let me remind you that 9 power and SoB paired up together in a card, in ELO, is considered as a terminator already. irate:" />
And with that in mind, I won't have to elaborate why I choose Lizbeth instead of Bloodh..
Therefore.. wait.. why are you still questioning yourself? Choose Lizbeth!
Just a point that I want to add, since we do not know what deck you're using, what we are stating are actually the card that are, in our perspective, the most beneficial in play. So those opinions are not facts, and the cards we like doesn't suit every kind of deck, so perhaps you may not find fit. I mean it all basically comes down to combos, or recipes. Just because we like lemonade dosn't mean we'll pour it over all our pasta. We have to personally see what our deck lacks of, and then fill up the void using the best 5* card we think is best candidate. This apply to you too. You like pasta but the pasta is incomplete without pasta sauce, you too like pasta sauce to be added in, so you naturally put the sauce into the pasta to make the best out of it. Sorry, I was a little bit of hungry when typing this but still, I really hope you will get the point.
