Hmm... It basically turns your deck into a damage shield for a few turns. Considering that deck sizes are relatively limited, this could end up being a very risky thing to do. Skelly decks and adrenaline decks could ptentially end up decking you out in record time.
Its definitely an interesting concept... I feel like it belongs in an element of some kind rather than "other", however... Maybe time or aether?
*aside*
I so want this to get put into openEtG... ohhhhh the fun mill decks that it would get when combined with the card "Give"
