I think it's a great card that would add so many awesome possibilities. It would probably be more for fun decks though because setting up that combo would take so long that you would probably lose the pvp game anyways.
While this card is a strong card, it's definitely not as strong as say a SOG for stalling. (eventually it would be as strong, but 3 quanta to get 5 heal every turn is just amazing)
Also, this card takes 3 cards to set-up, with those 3 cards, you could have much more easily gotten a permafrost shield, and two SOG instead of that combo.
