Fractal is a pretty good card, but there's a lot of ways to beat it. Discord and Nightmare are two of my favourites that I've used with success, particularly in War events. Discord scrambles quanta, making it hard to play fractal in the first place, and tough to play what you fractal even if you do, while nightmare fills the opponent's hand with (usually) useless cards that take the space of creatures generated by fractal, so that fractal hardly gives anything. There's a lot of other ways to beat it as well, but those are two really easy ways. If cards didn't exist that could make fractal useless, I'd agree that something would have to be done.
