Lambs to the Slaughter and Path of Worship cards boost your HP to high heavens (through Dominant and Empowered buffs), so you can just pop in Blood Pact and instakill whoever, even with the bugged starting HP (as some have access to MAD healing).
Why I probably dismissed Lambs to the Slaughter and Path of Worship in my post, is because those two are both in Succubus deck AND "Remove on use" cards.
And yes, I noticed the maxHP% damage only after fighting Valeria. :|
