I wouldn't have it reduce your max HP, tbh. Did you mean increase?SoV is already pretty weak as it is and a buff doesn't have to be even weaker than what it's trying to buff.I'd be pretty happy with this just being SoV on a creature.And the element changing is quite lovely, yes, but bear in mind changing elements isn't necessarily an "upgrade". I'd recommend increasing soul parasite's stats by a notch. Could probably increase stats, though upped being in makes it useable in decks other than ghostmareOtherwise, Different elements on cards are beautiful and I love this.
