At the beginning of your upkeep, reveal the top card of your library. Any opponent may have you put that card into your graveyard. If a player does, Sin Prodder deals damage to that player equal to that card's converted mana cost. Otherwise, put that card into your hand.
4/8/2016 Each opponent in turn order, starting with the one after you in turn order, may choose to have you put that card into your graveyard. Once a player does so, Sin Prodder deals damage equal to that card’s converted mana cost to that player immediately and Sin Prodder’s trigger has no further action.
