Ellie, Vengeful Scavenger

Whenever Joel, the Survivor enters the battlefield, transform Ellie, Vengeful Scavenger.
Whenever you sacrifice a junk token, if Ellie,
Vengeful Scavenger is equipped, she deals damage
equal to her power to any target.
Whenever a creature dies, if it was dealt damage by
a source you controlled this turn, you may exile the
top card of your library. Until the end of your next
turn, you may play that card.
