Because of your 6 novas, you can "splash" other cards as well. I think, I would do something like taking out the reverse times for either a fog shield, a lightning or a basilsk blood, or maybe a gravity pull. But I honestly can't tell if this would be a better option than reverse time or not.

Maybe you want to switch some time factories for time pendulums, to get more entropy quanta. To buy some time, one or two discords may be a good option.
