This is the victim.
It is used on sparks. And nothing else. There is no other meaning for this card.
Basilisk Blood does a better job if you need a massive HP increase.
My buff proposals are these:
1) More cards that work better with higher HPs (or HPs at all.).
2) A small attack buff (+1/+3), (+1/+6).
3) Get the "Endow" ability for
to the creature. It has an armor, why shouldn't it have a sword?
