One health would delete the fun of this card, i think the Quanta/Strength is somewhat balanced like that.
There should definitely be something like that in the card notes if you post it into the next thread: "If this card evades being targeted by a spell card, the card is returned to it´s owners hand, and can´t be played till next turn"
I'd definitely keep it 2
, even though I would have liked 1.
IMHO, though, it could be something like: Dodge a card that targets this by returning to the hand.
This way it'll always dodge buffs, aside SoP and Eclipse, it won't dodge RoF. I think that, like this, it'd be pretty good, but definitely not OP, it'd work better as a monodark, or darkness-death duo with Deathstalker.
