Yeah, I have to agree. While I sort of love the idea of throwing out tons of creatures, a card like fractal does break this idea nearly completely. You could fractal a creature, then play this, and play a bunch of high cost creatures for basically free.
I really don't see a work-around for it. And I do so like the idea of just laying everything out on the table.
Hmm...What if it halved the cost of cards for one turn?
