Pyromancer's Teachings

At the beginning of your upkeep, exile the
top card of your library. You may cast spells exiled this way this turn. At the beginning
of the next end step, if that card is still exiled, put it into your graveyard and take 2 damage or Sacrifice Pyromancer's Teachings.
The art of Pyromancy is a dangerous one. Are
you sure you want to go down this road?
