Heedless Spellcaster

Flying
At the beginning of your upkeep, reveal the top card of your library until you reveal a nonland card with converted mana cost 3 or less. You may cast this card without paying its mana cost. Exile each other card revealed this way and put that many insanity counters on Heedless Spellcaster. (A player with ten or more insanity counters on permanents he or she controls loses the
game.)
