So I assume the number of Rofellos you are playing is not one, but more?
If room permitted it, I'd run more, but I only run him as a singleton. Quite contradictory as he is such a solid early drop, but being legendary and rather weak on his own, I'd prefer to opt to just tutor him and go nuts. But I'm always happy opening him, and will almost always (almost being certain game states on turn 2) run him out turn 2 over a Survival, Goyf, or Confidant.
