Huckleberry Finn

Vigilance, Haste, First Strike
When Huckleberry Finn enters the battlefield,
he explores. If a player controls a creature named
Pap, sacrifice Huckleberry Finn. When
Huckleberry Finn dies, if he was sacrificed,
return him to your hand.
Tom Sawyer he hunted me up and said he was
going to start a band of robbers, and I might join
if I would go back to the widow and be respectable.
So I went back. -Huck Finn, Chapter 1
