Heretic's Punishment

Text:

: Choose any target, then mill three cards. Heretic's Punishment deals damage to that permanent or player equal to the highest mana value among the milled cards.

Rulings:

• 9/22/2011 If the targeted permanent or player is an illegal target by the time the ability resolves, the entire ability won’t resolve. No cards will be put into your graveyard, and no damage will be dealt.
• 9/22/2011 If you have two or fewer cards in your library when the ability resolves, all of them will be put into your graveyard. Heretic’s Punishment will still deal damage equal to the highest converted mana cost among those cards.
• 9/22/2011 The converted mana cost of a double-faced card in your graveyard is the converted mana cost of the front face.
• 9/22/2011 If all three cards have a converted mana cost of 0, no damage will be dealt.
