i like the general concept of the card especially because of how it clashes very easily with fractal spam. However, it would still work because you can only have 8 cards in your hand max, and unless you empty you ENTIRE hand and play the fractal, as well as manage to play each and every single one of those creatures, all of those creatures will stay alive, and this is unupped.
I would say either bring the HP down or bring the cost up.
