It's just mad drawing until you can get Miracle out. Also, consider you actually have a low damage output even with Neuro, meaning you are very likely to draw Miracle before you win. This is further assisted by quicker drawing via Hourglasses and that excess Nightmares will heal you.
If you can, feel free to exchange a Nova or a RoL for another Miracle if you want to increase the draw chance.
Regarding stats, Xeno's simulator is not reliable as AI will not Nightmare RoL.
