This'd be pretty powerful in a stall, e.g. sancstall. Time's version of it has lots of room for other cards and ensuring your opponent will bottomdeck 6 of their creatures allows you to weather both early- and mid-game rather easily, which is the weakness of the deck and most stalls. Once set up with Procrast, Eterns and Sancs you keep drawing Dials and Miracles with HG's. You'd probably have to choose RT's or Dials for space reasons, favoring either mid- or late-game.
It'd also be powerful in Ghostal; drawing with Ghostal means you can put Dims up early against little offense, so even if your opponent draws PC he won't be able to do a lot of damage. Then comes the Ghost/Psiontal.
