The Relinquished Daughter

The Relinquished Daughter enters with X+10
Thaw counters on it. Any player may contribute
to paying the mana cost. At the beginning of
each player's turn who helped pay the cost of
The Relinquished Daughter, remove a Thaw
counter from it and that player gains 3 life,
Scries 1 and draws 1 card.
When all Thaw counters are removed from The Relinquished Daughter, destroy it and create a 9/1 Legendary Mermaid creature token named "The Relinquished" with Deathtouch and Unblockable.
