Elena Finch, Ritual Victim can't block.
Whenever Elena dies on your turn, you get an
experience counter. Then, create an X/X white
and black Spirit creature token with flying,
where X is the number of experience counters
you have.
{x}{w/b}: Return Elena from your graveyard to the
battlefield. X is equal to the number of
experience counters you have.
