Being on the play, I played an Unlucky Cabbage Merchant turn 2.
Turn 3 I played a Firebending lesson. On opponent's turn I played Firebending lesson for 1 mana and sacrificed the food for 2 mana, triggering the Unlucky Cabbage Merchant's ability to search for a land. I did it and on my turn the Unlucky Cabbage Merchant had dissapeared, it was not in the battlefield, in the graveyard or in exile.
