Hitoriko, the Eternal Blaze

At the beginning of your upkeep, return
Hitoriko from your graveyard to your hand.
At the beginning of your end step, put a +1/+1
counter on Hitoriko, then she deals damage
equal to her power to target creature. If she
deals 6 or more damage this way, sacrifice her
and that damage can't be prevented.
