With the changes, it seems pretty fun now. But, not so much fun when you can replenish your "quanta" supply with Miracles. I would use a Fractal deck without any Aether Towers if this card was around, still. I think it needs more work, but it's gotten better. Why not add "You can't be healed for the rest of the turn after you use this card"? Still, though, something of this caliber should be really rare.
