Johann, Apprentice Sorcerer

You may look at the top card of your library any time.
Once each turn, you may cast an instant or sorcery spell from the top of your library. (You still pay its costs. Timing rules still apply.)

"Okay. First I'll calm the elementals. Then I'll put out the fire. Then I'll unflood the basement. Then I'll do the chores *myself*."
